 1.94  10-Feb-2024  andvar fix various typos in comments and log messages.
 1.93  20-Aug-2022  riastradh usbnet(9): New usbnet_ispromisc(un).

Replaces ifp->if_flags & IFF_PROMISC in multicast filter updates.
 1.92  03-Mar-2022  riastradh usbnet: Omit needless detachcv name parameter to usbnet_attach.
 1.91  03-Mar-2022  riastradh usbnet: Factor usbnet_init_rx_tx out into usbnet_if_init.

Make it private; no need for drivers to call it any more.
 1.90  03-Mar-2022  riastradh usbnet drivers: Omit redundant device reset via *_uno_stop on init.

Only those drivers where *_uno_stop is just *_reset, and *_uno_init
immediately calls *_reset afterward, are affected.
 1.89  03-Mar-2022  riastradh usbnet drivers: From *_uno_init, call *_uno_stop, not usbnet_stop.

Make usbnet_stop private now that no drivers use it.

None of the driver-independent logic in usbnet_stop has any effect at
this point because we are guaranteed not to be running, so only the
driver-dependent logic in *_uno_stop (at most) is needed.

For drivers with no *_uno_stop, just omit the call to usbnet_stop
altogether.

Some of this logic is obviously redundant with the subsequent call to
*_reset -- to be addressed in a subsequent commit.
 1.88  03-Mar-2022  riastradh usbnet drivers: Omit needless isdying tests in *_uno_init.

usbnet(9) already checks this immediately before calling *_uno_init.
 1.87  03-Mar-2022  riastradh usbnet drivers: Omit needless usbnet core lock and assertions.

During attach, the caller has exclusive access to the usbnet until
usbnet_attach_ifp. At other times, register access is serialized
either by the usbnet multicast lock or by IFNET_LOCK.
 1.86  03-Mar-2022  riastradh usbnet drivers: Avoid undefined behaviour if read reg fails.

Some callers don't check the error code, e.g. ~all the mii phy
drivers using PHY_READ. Just return zero if the device is gone or
the xfer fails for any other reason.
 1.85  03-Mar-2022  riastradh usbnet drivers: Assert IFNET_LOCKED in if ioctl routines.

These only happen either during the transition up or down (init or
stop), or while that transition is excluded (ioctl).

This may be called from ioctl or from init, which both hold the ifnet
lock.

XXX smsc_setoe_locked should maybe trigger reinit because the rx loop
behaves differently depending on whether checksumming is enabled.

XXX mue_sethwcsum_locked needs to exclude mcast updates.
 1.84  03-Mar-2022  riastradh usbnet drivers: Omit redundant multicast filter update on init.
 1.83  03-Mar-2022  riastradh usbnet: Apply hardware multicast filter updates synchronously again.

To make this work:

1. Do it only under a new lock, unp_mcastlock. This lock lives at
IPL_SOFTCLOCK so it can be taken from network stack callouts. It
is forbidden to acquire the usbnet core lock under unp_mcastlock.

2. Do it only after usbnet_init_rx_tx and before usbnet_stop; if
issued at any other time, drop the update on the floor.

3. Make usbnet_init_rx_tx apply any pending multicast filter updates
under the lock before setting the flag that allows SIOCADDMULTI or
SIOCDELMULTI to apply the updates.

4. Remove core lock asserts from various drivers' register access
routines. This is necessary because the multicast filter updates
are done with register reads/writes, but _cannot_ take the core
lock when the caller holds softnet_lock.

This now programs the hardware multicast filter redundantly in many
drivers which already explicitly call *_uno_mcast from the *_uno_init
routines. This is probably harmless, but it will likely be better to
remove the explicit calls.
 1.82  03-Mar-2022  riastradh usbnet drivers: Stop abusing ifp->if_flags & IFF_ALLMULTI.

This legacy flag is a figment of userland's imagination. The actual
kernel state is ec->ec_flags & ETHER_F_ALLMULTI, protected by the
ETHER_LOCK, so that multicast filter updates -- which run without
IFNET_LOCK -- need not attempt to write racily to ifp->if_flags.
 1.81  03-Mar-2022  riastradh usbnet drivers: Omit needless uno_mcast locked subroutines.

uno_mcast is now called with the core lock already held so there is
no need for a separate locked subroutine.
 1.80  03-Mar-2022  riastradh usbnet: Take the core lock around uno_mcast.

Every driver does this already. This will enable us to change the
lock that serializes access to the registers so we can go back to
doing this synchronously in SIOCADDMULTI/SIOCDELMULTI.
 1.79  03-Mar-2022  riastradh usbnet drivers: Omit needless uno_init locked subroutines.

uno_init is now called with the core lock already held so there is no
need for a separate locked subroutine.
 1.78  03-Mar-2022  riastradh usbnet drivers: No need for usbnet_busy during attach.

usbnet_detach cannot run until the attach routine has finished
(unless a driver goes out of its way to tie its shoelaces together
and explicitly call it during the attach routine, which none of them
do), so there is no need to hang onto a reference count that we
release before attach returns.
 1.77  03-Mar-2022  riastradh usbnet drivers: No need for usbnet_busy in uno_ioctl.

This callback always runs with the IFNET_LOCK held, and the interface
cannot be detached until the IFNET_LOCK is released, so there is no
need to hang onto a reference count here. (None of the subnet
drivers touch the IFNET_LOCK except to verify it is held sometimes.)
 1.76  03-Mar-2022  riastradh usbnet drivers: No need for usbnet_busy in uno_mcast.

This callback always runs with IFNET_LOCK held, and during a task
that usbnet_detach prevents scheduling anew and waits for finishing
before completing the detach, so there is no need to hang onto a
reference count here.
 1.75  03-Mar-2022  riastradh usbnet drivers: No need for usbnet_busy in uno_init.

This callback always runs with the IFNET_LOCK held, and the interface
cannot be detached until the IFNET_LOCK is released, so there is no
need to hang onto a reference count here. (None of the usbnet
drivers touch the IFNET_LOCK except to verify it is held sometimes.)
 1.74  03-Mar-2022  riastradh usbnet: Split multicast filter reprogramming into separate operation.
 1.73  03-Mar-2022  riastradh usbnet drivers: Stop timeout loops early if device is detaching.
 1.72  03-Mar-2022  riastradh usbnet: Enter uno_init with the core lock held.

This reduces code in all drivers except urndis(4) and aue(4).

However, it's still safe for urndis to drop the core lock because the
ifnet is locked, and the ifnet lock covers the DOWN->UP (uno_init)
and UP->DOWN (uno_stop) transitions.
 1.71  03-Mar-2022  riastradh axen(4), mue(4), smsc(4): Omit irrelevant cases in ioctl.

SIOCSIFFLAGS and SIOCSETHERCAP always end up in ether_ioctl_reinit,
which triggers the same logic to reprogram the multicast filters
anyway.
 1.70  25-Apr-2021  rin Sample # of RX packets as entropy source.
 1.69  27-Jun-2020  jmcneill prop_data_data_nocopy -> prop_data_value
 1.68  15-Mar-2020  thorpej Define and implement a locking protocol for the ifmedia / mii layers:
- MP-safe drivers provide a mutex to ifmedia that is used to serialize
access to media-related structures / hardware regsiters. Converted
drivers use the new ifmedia_init_with_lock() function for this. The
new name is provided to ease the transition.
- Un-converted drivers continue to call ifmedia_init(), which will supply
a compatibility lock to be used instead. Several media-related entry
points must be aware of this compatibility lock, and are able to acquire
it recursively a limited number of times, if needed. This is a SPIN
mutex with priority IPL_NET.
- This same lock is used to serialize access to PHY registers and other
MII-related data structures.

The PHY drivers are modified to acquire and release the lock, as needed,
and assert the lock is held as a diagnostic aid.

The "usbnet" framework has had an overhaul of its internal locking
protocols to fit in with the media / mii changes, and the drivers adapted.

USB wifi drivers have been changed to provide their own adaptive mutex
to the ifmedia later via a new ieee80211_media_init_with_lock() function.
This is required because the USB drivers need an adaptive mutex.

Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv.

mcx also now calls ifmedia_init_with_lock() because it needs to also use
an adaptive mutex. The mcx driver still needs to be fully converted to
NET_MPSAFE.
 1.67  14-Mar-2020  christos fix more broken kernhist formats (now I got them all).
 1.66  14-Mar-2020  christos revert the 0x% -> %# change for fixed width formats pointed out by uwe.
 1.65  13-Mar-2020  christos PR/55068: sc.dying: Fix printf formats:
- no %s/%p for kernel log
- 0x% -> %#
- always %j for kernel log
 1.64  05-Feb-2020  msaitoh Cast to uint32_t to avoid undefined behavior in smsc_setmacaddress.
Found by kUBSan.
 1.63  29-Jan-2020  thorpej Adopt <net/if_stats.h>.
 1.62  07-Jan-2020  maxv branches: 1.62.2;
Localify, constify.
 1.61  23-Aug-2019  mrg s/UBSNET_MII_DECL_DEFAULT/USBNET_MII_DECL_DEFAULT/. from sc.dying.
 1.60  20-Aug-2019  mrg couple more changes to usbnet(9):

- MII read/write reg return int instead of usbd_status (requested by skrll)
- usbnet_attach_ifp(9) changes arg, two mii-specific flags are placed by a
pointer to new struct usbnet_mii. if not NULL, then attach an MII to this
interface like previous have_mii parameter. use this to allow ure(4) to
properly pass PHY location to mii_attach().

welcome netbsd 9.99.10.
 1.59  19-Aug-2019  mrg move the check against un_phyno from usbnet back into the drivers
that do this (axe, axen, mue, smsc, ure.) it made mii scanning
only work for phy 0, and aue needs it for at least one device.

fix smsc to return usbd_status not -1 on failure. XXX smsc was
writing to '*val' even in error cases, it does not now.

remove a double call to IFQ_SET_READY() (noticed by chuq).

avoid unlock+instant relock by using usbnet_lock_mii_un_locked().
 1.58  15-Aug-2019  mrg - usbnet_rx_loop_cb's usbd_xfer parameter is never used and available
in the usbnet_chain if needed. remove it
- usbnet media status change already set link to false, don't repeat
this in every driver
- don't clear link in stop, nothing was re-enabling it for non-MII
- add optional uno_tick_cb(struct usbnet *un) that is called from the
usbnet tick timer
- remove wrong debug sysctl prototype

rx_loop and timer are kernel versions changes, but hopefully this is
the last one for usbnet. working with 3 more drivers now (cue, mue
and url), leaving only aue, kue, upl and umb undone (aue may work
with previously supported devices, mine doesn't work with our driver,
kue and upl have patches for testing and umb is undone.)
 1.57  14-Aug-2019  mrg introduce usbnet_set_dying(). will be used by url(4) conversion.
bump version.

introduce USBNET_MODULE() that encompasses almost all the module
specific code for usbnet modules. they still need to include
the relevant ioconf.c, but everything else is now just, eg,

USBNET_MODULE(axen)
 1.56  11-Aug-2019  mrg don't set dv_private. it's a bad pattern and only didn't
trip kmem_free() lossage because struct usbnet is at the
start of the softc.

for now, enforce this as part of the ABI.

catch up urndis with tx_prepare checking buffer length,
and also add an assert to usbnet_start_locked() to match.
 1.55  11-Aug-2019  skrll Fix and improve USMSC_DEBUG
 1.54  11-Aug-2019  skrll Convert smsc_dbg_printf to usbhist
 1.53  11-Aug-2019  skrll Correct the length of the buffer to copy into the mbuf. Spotted by
sc dying.
 1.52  11-Aug-2019  skrll Add a check in smsc_tx_prepare for the mbuf being too big. Discussed
with mrg@
 1.51  10-Aug-2019  mrg reduce the scope of struct usbnet:
- move a large number of members internal to usbnet.c's new
"struct usbnet_private".
- provide accessors for a few of these
- move struct usbnet_cdata into usbnet.c as well, but move
bufsz, list count, and xfer flags back out into struct usbnet,
and have them set as part of the setup efore usbnet_attach()
- split the intr pipe parts into their own structure
- move all the main usbnet*lock* code into usbnet.c too

usbnet_attach() goes down to 2 args, and the inputs needed are
now the full contents of 'struct usbnet' besides the driver
owned 'un_flags' and usbnet owned 'un_pri'.

welcome netbsd 9.99.6.
 1.50  09-Aug-2019  skrll G/C
 1.49  09-Aug-2019  mrg update usbnet some:
- move rx/tx xfer flags into usbnet_cdata
- move the callbacks into usbnet_ops structure
- move rx/tx xfer flags arguments from usbnet_init_rx_tx()
and move them all into usbnet_attach() arguments
- s/miibus/mii/ in some places for consistency

other clean up:
- create wrapper functions for callbacks, move knowledge about
special handling (OK to be missing, error eating) there.
- use cdata pointer if already available
- provide some more macros (will be real functions later) for
accessing usbnet members, use existing ones more

bump kernel version.
 1.48  07-Aug-2019  mrg fix module build: s/axen/smsc/ in one place.
 1.47  07-Aug-2019  skrll Convert smsc(4) to usbnet
 1.46  01-Aug-2019  mrg remove unused code and use common ethernet media code where equivalent.
 1.45  23-May-2019  msaitoh branches: 1.45.2;

- Simplify MII structure initialization.
- u_int*_t -> uint*_t.
- KNF
 1.43  05-Mar-2019  msaitoh Centralize ETHER_ALIGN into net/if_ether.h. Note that this commit also changes
if_upgt.c's ETHER_ALIGN from 0 to 2.
 1.42  02-Feb-2019  dholland PR kern/53930 from "sc dying": uninitialized condvar in usmsc(4)
 1.41  27-Jan-2019  pgoyette Merge the [pgoyette-compat] branch
 1.40  22-Jan-2019  skrll Whitespace
 1.39  22-Jan-2019  msaitoh Change MII PHY read/write API from:

int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

 1.25  09-Feb-2016  ozaki-r 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.

 1.12.2.1  07-Apr-2014  tls Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
that had stubbed out code, other minor cleanups.

New function usb_rem_task_wait(dev, task, queue).

If task is scheduled to run, removes it from the queue. If it may
have already begun to run, waits for it to complete. Caller must
guarantee it will not switch to another queue. If caller guarantees
it will not be scheduled again, then usb_rem_task_wait guarantees it
is not running on return.

This will enable us to fix a litany of bugs in detach where we
currently fail to wait for a pending task.

Use usb_rem_task_wait in various drivers.

at SOFTINT_NET has blocked holding a lock, e.g. softnet_lock and most of
the network stack.
- kern/49065 - ifconfig tun0 ... sequence locks up system / lockup:
softnet_lock held across usb xfr

Centralised the buffer allocation routine which now supports DMA

ubm_{alloc,free}m methods from usbd_bus_methods.

The buffer allocation is only allowed in thread context and,
therefore, negates the usefulness of the reserve dma code which
is removed in this change.

USBD_NO_COPY is also no longer required as usbd_transfer and
usbd_transfer_complete now track buffer usage and handle any
copying.

New function usb_rem_task_wait(dev, task, queue).

If task is scheduled to run, removes it from the queue. If it may
have already begun to run, waits for it to complete. Caller must
guarantee it will not switch to another queue. If caller guarantees
it will not be scheduled again, then usb_rem_task_wait guarantees it
is not running on return.

This will enable us to fix a litany of bugs in detach where we
currently fail to wait for a pending task.

Use usb_rem_task_wait in various drivers.
