adapt locking to the modern world. some what inspired by if_smsc.c:
- add locks for softc, rx and tx
- add safe detach support
- safe detach vs mii lock requires 2 methods to lock the MII lock,
- check axen_dying and new axen_stopping more often
- consolidate checks to reduce the number of error paths that need
to release a resource
- move axen_watchdog() out of if_timer into the tick task to
prepare for MPSAFEification
TODO:
- remove spl usage
- enable mpsafe
special thanks to skrll and mlelstv for clearing up various
confusion and providing examples.
Stop competing between threads which one emits event signal quicker and
overwriting the signal from another thread.
This fixes missed in action signals.
NetBSD truss can now report reliably all TRAP_SCE/SCX/etc events without
reports of missed ones.
This was one of the reasons why debuggee with multiple threads misbehaved
under a debugger.
gpt_change_ent(). The purpose of the third argument is to specify
whether the entry to be changed is a primary GPT entry or a secondary
GPT entry. It is assumed that a secondary GPT entry will always
follow a corresponding primary entry.
This is in preparation for an upcoming change that will require it.
This flag used to be useful in /proc (BSD4.4-style) debugging semantics.
Traced child events were notified without signaling the parent.
This property was removed in NetBSD-8.0 and had no users.
This change simplifies the signal code, removing dead branches.

Previous version compared the pad's output binary passed mulaw-slinear
conversion and frequency conversion with the prepared "good result".
In such case, a test may fail when the implemantation changes. In fact,
the frequency conversion algorithm was changed in isaki-audio2, so
output waveforms is not completely the same (but that's no problem with
the audio waveforms).
New version uses slinear_le/2ch/44100Hz input data and compares the
output binary with the input data. pad with no conversions should
output the same binary.
Fix PR kern/54187.
- use const, __func__, more
- axen_mii_lock is a normal mutex not rwlock, and make sure it's
properly cleaned up for failed attach
- check axen_dying in axen_miibus_statchg()
- rename axen_ax88179_eeprom() to axen_get_eaddr() and move the code
here into the support the current method.
- adjust some comments
mknod with mode & S_IFIFO and dev=0 shall behave like mkfifo.
Update the documentation to reflect this state.
Add ATF tests.
This is an in-kernel implementation as typically user-space programs use
mkfifo(2) directly, however whenever there is need to bypass libc (like in
valgrind) then portable POSIX software calls the mknod syscall.
