Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

Implement new NuBus slot space mapping/probing code, utilizing bus.h (and

- NuBus drivers must map and unmap slot space, rather than relying

- Functions exported to NuBus drivers from nubus.c now need to be
supplied with a bus space tag/handle pair.
- Old bus map/peek functions can be garbage collected, as can pmap
support for the same.

Because of some current limitations of the bus space specification, we
are violating the abstraction in grf_mv (NuBus grf driver). All such
violations are clearly marked /* XXX */, and must be addressed when
the specification is updated.

Changes from Bob Nestor to come closer to supporting his Apple SONIC-based

- Map registers using an array of bus_size_t offsets, and set up the
mapping in the attach code (thanks to Jason Thorpe for suggesting
this!).
- Disable the ae-specific watchdog, which is no longer necessary in
the general case.

Still remaining: split out functions used to copy data to/from the
card, and retain a way to have a local driver name with the MI code.

Help this compile and get the nubus address into myaddr instead of

- Note that some drivers still update packet statistics in their own
way (periodical update)

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Redefine bpf linkage through an always present op vector, i.e.

doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address. (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior. Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability. KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr. That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR. For example, pull ..._init() out of any switch
statement that looks like this:

switch (...->sa_family) {
case ...:
..._init();
...
break;
...
default:
..._init();
...
break;
}

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

switch (x & (IFF_UP|IFF_RUNNING)) {
case 0:
...
break;
case IFF_RUNNING:
...
break;
case IFF_UP:
...
break;
case IFF_UP|IFF_RUNNING:
...
break;
}

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure. Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls. In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source. In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

Identify and use the Apple Twisted Pair NB card properly, from PR 3789
submitted by Denny Gentry <denny1@home.com>; investigation on the hardware
done by Bob Nestor.

Update from Denny Gentry <denny1@home.com>, PR 3685:

Simplify the way transmit buffers are managed, remove assumptions about
NBPG, simplify sonic_get handling, update snioctl to be more like other
current drivers, and probably a few other changes I've now forgotten about.

Implement new NuBus slot space mapping/probing code, utilizing bus.h (and
our MD bus_space_probe() extension). This has several side effects:

- NuBus drivers must map and unmap slot space, rather than relying
on this happening before they are attached.
- Functions exported to NuBus drivers from nubus.c now need to be
supplied with a bus space tag/handle pair.
- Old bus map/peek functions can be garbage collected, as can pmap
support for the same.

Because of some current limitations of the bus space specification, we
are violating the abstraction in grf_mv (NuBus grf driver). All such
violations are clearly marked /* XXX */, and must be addressed when
the specification is updated.

Treat drhw 118 and 119 the same for Apple ethernet cards.

Remove dependency on if_aereg.h for vendor constants; these are really
driver-, not architecture-specific.

Remove obsolete drsw diagnostic; make formatting consistent; KNF.

Make sure that we unmap the space that we mapped if we can't identify the card.

Initialize 'offset' to make gcc happy.

Use an offset parameter when loading the reg_map--some cards use the "other"
16 bits of the words.

Oops. We do not want to unmap something that we've used bus_space_subregion
to get.

Some updates based on information from Bob Nestor <rnestor@metronet.com>
about his SONIC-T LC/PDS card.

Changes from Denny Gentry <denny1@home.com>:
Change in the way receive buffer areas are handled. Before we gave
the chip 16 buffers, each 1536 bytes (big enough for one packet).
Now we're handing the chip 8 buffers, each 4 Kbytes, and letting
the chip fit as many packets as it can in each one. This should
help keep it from running out of buffer space. Also make some of
the performance-crucial routines inline. It made no measurable
difference except to make me feel better

Changes from Bob Nestor <rnestor@metronet.com> to get closer to support
for his Apple SONIC-based nubus card.

Changes from me to try to get SONIC's MAC address from MacOS settings if
we can't read the PROM space.

Some new SONIC code from Denny Gentry <denny1@home.com> with a couple of
tweaks and bug fixes by yours truly.

Here's what Denny had to say:

nubus.h:
- add a drsw entry for my card
[ I also added a couple of constants for more display cards ]
if_sn.c:
- allocate sc->space using malloc (Scott wanted this).
- make csr accesses use NIC_PUT/GET, remove sc->sc_csr.
- add multicast and IFF_PROMISC support. multicast isn't
well tested, but I made sure the unicast case still
works.
- finish the new arp interface, remove sc->sc_enaddr
if_snreg.h:
- remove struct sonic_reg
if_snvar.h:
- add NIC_PUT and NIC_GET macros a la if_ae
- remove sc_txhead, it isn't used.
if_sn_nubus.c:
- clean up support for my SE/30 card.
- Move add_nubus_intr from if_sn.c (to keep if_sn.c MI)
if_sn_obio.c:
- make Q610, C610, Q650, C650, Q800 use EXBUS.
- PB500 had a "return" where "break" was intended. PB500
probably wasn't working.
- move add_nubus_intr from if_sn.c.
- add an "explanation" why Apple's ethernet addr is encoded
in token ring format in the PROM.

On request from Allen Briggs, converted this to new ARP
system. Somebody should actually test if this compiles (and works) on
Mac68k... I only carefully checked cvs diff -u.

Merge thorpej-cfargs2.

branches: 1.67.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

to grfmv_intr_generic_write{1,4} and added grfmv_intr_generic_or4 to
handle this card.

Support for the Lapis ProColorServer 8 PDS on the SE/30. This prevents
hangs when trying to use this video card in conjunction with an ethernet
card. Thanks to David Condon <david@apk.net> for information and testing.

Add support for Portrait Video Card. From SUNAGAWA Keiki
<kei_sun@ba2.so-net.or.jp> in PR 3821.

Implement new NuBus slot space mapping/probing code, utilizing bus.h (and
our MD bus_space_probe() extension). This has several side effects:

- NuBus drivers must map and unmap slot space, rather than relying
on this happening before they are attached.
- Functions exported to NuBus drivers from nubus.c now need to be
supplied with a bus space tag/handle pair.
- Old bus map/peek functions can be garbage collected, as can pmap
support for the same.

Because of some current limitations of the bus space specification, we
are violating the abstraction in grf_mv (NuBus grf driver). All such
violations are clearly marked /* XXX */, and must be addressed when
the specification is updated.

Thanks to Tobias Beal <tbeal41@maine.maine.edu>, we can clear interrupts
on at least one Radius Precisioncolor 8 board.

Treat drhw 118 and 119 the same for Apple ethernet cards.

Add in a couple more board types.

Ignore SE/30 faux-video card.

Comment video cards and add define for SuperMac Thunder/24.

Changes from Bob Nestor to come closer to supporting his Apple SONIC-based
nubus card.

Add DrHW for RasterOps CB264--From Scott Reynolds--and link it in to the
proper interrupt routine.

Some new SONIC code from Denny Gentry <denny1@home.com> with a couple of
tweaks and bug fixes by yours truly.

Here's what Denny had to say:

nubus.h:
- add a drsw entry for my card
[ I also added a couple of constants for more display cards ]
if_sn.c:
- allocate sc->space using malloc (Scott wanted this).
- make csr accesses use NIC_PUT/GET, remove sc->sc_csr.
- add multicast and IFF_PROMISC support. multicast isn't
well tested, but I made sure the unicast case still
works.
- finish the new arp interface, remove sc->sc_enaddr
if_snreg.h:
- remove struct sonic_reg
if_snvar.h:
- add NIC_PUT and NIC_GET macros a la if_ae
- remove sc_txhead, it isn't used.
if_sn_nubus.c:
- clean up support for my SE/30 card.
- Move add_nubus_intr from if_sn.c (to keep if_sn.c MI)
if_sn_obio.c:
- make Q610, C610, Q650, C650, Q800 use EXBUS.
- PB500 had a "return" where "break" was intended. PB500
probably wasn't working.
- move add_nubus_intr from if_sn.c.
- add an "explanation" why Apple's ethernet addr is encoded
in token ring format in the PROM.

NUBUS_SLOT_TO_PADDR -> NUBUS_SLOT2PA

Add a bus space tag field to nubus_attach_args

branches: 1.15.6;
Define struct nubus_attach_args

Get rid of some old, now meaningless macros.

Prototype for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.

Patch to at least recognise FOCUS EtherLAN. From Erik Bertelson
<erik@sockdev.uni-c.dk>

Add Technology Works ethernet card. From
Kazunari Nakamura <kazu@nkk.co.jp>.

Fix the internal video probe again.

Fix buglet that was missed when converting nubus to non pa==va mapping.

Make NUBUS_BASE_TO_SLOT and reverse not depend on VA==PA for NuBus.
Add constant for DRSW_FARALLON.

Add some code/defines to differentiate Asante and Interlan/Gator cards
correctly with the new nubus code.

Add new nubus handling that's much more robust.
Update via, if_ae, and grf accordingly.
Revamp grf.

First pass of KNFication. Needs more.

new RCS ID format.

Update to current work in progress. This includes an update to
