| 1.8 | 07-Aug-2021 | thorpej | Merge thorpej-cfargs2. 
 | 
| 1.7 | 24-Apr-2021 | thorpej | branches:  1.7.8; 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?).

 | 
| 1.7 | 22-Jul-2022 | thorpej | Normalize how motoi2c controllers are attached. 
 | 
| 1.6 | 22-Jul-2022 | thorpej | Split the i2c controller into 2 separate instances.  This aligns with how the device is represented when using DeviceTree, and also allows us
 to de-weirdify the shared motoi2c code.
 
 XXX Because e500 interrupt code doesn't support shared interrupts, we
 no longer establish one for the i2c controller, but this isn't a great
 loss as motoi2c doesn't support using interrupts right now anyway.
 
 | 
| 1.5 | 06-Jul-2020 | rin | Style and cosmetic changes. No binary changes intended. 
 | 
| 1.4 | 03-Sep-2018 | riastradh | 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!)

| 1.55 | 16-Jun-2021 | riastradh | branches:  1.55.2; if_attach and if_initialize cannot fail, don't test return value
 
 These were originally made failable back in 2017 when if_initialize
 allocated a softint in every interface for link state changes, so
 that it could fail gracefully instead of panicking:
 
 https://mail-index.NetBSD.org/source-changes/2017/10/23/msg089053.html
 
 However, this spawned many seldom- or never-tested error branches,
 which are risky to have around.  And that softint in every interface
 has since been replaced by a single global workqueue, because link
 state changes require thread context but not low latency or high
 throughput:
 
 https://mail-index.NetBSD.org/source-changes/2020/02/06/msg113759.html
 
 So there is no longer any reason for if_initialize to fail.  (The
 subroutine if_stats_init can't fail because percpu_alloc can't fail
 either.)
 
 There is a snag: the softint_establish in if_percpuq_create could
 fail, potentially leading to bad consequences later on trying to use
 the softint.  This change doesn't introduce any new bugs because of
 the snag -- if_percpuq_attach was already broken.  However, the snag
 can be better addressed without spawning error branches, either by
 using a single softint or making softints less scarce.
 
 (Separate commit will change the signatures of if_attach and
 if_initialize to return void, scheduled to ride whatever is the next
 convenient kernel bump.)

 soliloquy, and compile-testing on evbppc/i386/earmv7hf, by me.

| 1.54 | 24-Apr-2021 | thorpej | branches:  1.54.2; 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?).

| 1.40 | 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:

| 1.39 | 22-Dec-2018 | maxv | Replace M_ALIGN and MH_ALIGN by m_align. 
 | 
| 1.38 | 22-Dec-2018 | maxv | Replace: M_MOVE_PKTHDR -> m_move_pkthdr. No functional change, since the former is a macro to the latter.
 
 | 
| 1.37 | 03-Sep-2018 | riastradh | 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!)

| 1.29 | 15-Dec-2016 | ozaki-r | branches:  1.29.8; Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input
 
 The benefits of the change are:
 - We can reduce codes
 - We can provide the same behavior between drivers
 - Where/When if_ipackets is counted up
 - Note that some drivers still update packet statistics in their own
 way (periodical update)
 - Moved bpf_mtap run in softint
 - This makes it easy to MP-ify bpf
 
 Proposed on tech-kern and tech-net

| 1.28 | 26-Jul-2016 | nonaka | IFQ_PURGE() must be called only after call if_initialize(). it lock ifp->if_snd.ifq_lock.
 
 | 
| 1.27 | 10-Jun-2016 | ozaki-r | branches:  1.27.2; 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.
 
 | 
| 1.26 | 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.
 
 Additional information including performance numbers can be found
 in the thread at tech-kern@ and tech-net@:

 VLAN ID uses pkthdr instead of mtag now. Contributed by s-yamaguchi@IIJ.
 I just commit by proxy. Reviewed by joerg@n.o and christos@n.o, thanks.
 See http://mail-index.netbsd.org/tech-net/2017/09/26/msg006459.html
 --
 only get vtag when we have vtag like the other drivers.
 --
 - only get the vtag if we have it like the other drivers
 - mask the hardware vlan tag
 --
 - add a constant for the vlan mask.
 - enforce that we have a tag before we get it.
 only get vtag when we have vtag like the other drivers.
 like if_bge.c:1.312 and if_stge.c:1.64.
 fixed by s-yamaguchi@IIJ, thanks.

 tag-value variadic arguments that can be passed to the various
 config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
 for now, plus a CFARG_EOL sentinel).
 - Collapse config_search_*() into config_search() that takes these
 variadic arguments.
 - Convert all call sites of config_search_*() to the new signature.
 Noticed several incorrect usages along the way, which will be
 audited in a future commit.

 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?).

 If a device carries only one interface attribute, there is no need
 to specify it when calling config_search(); that specification is
 meant only to disambiguate which interface attribute (which is a
 proxy for "what kind of attach args are being used") is having
 children attached.  cfparent_match() will take care of ensuring that
 any potential children can attach to one of the parent's iterface
 attributes, and if the parent only carries one, no disambiguation is
 necessary.
