if_link_queue is a queue to store events of link state changes, which is
used to pass events from (typically) an interrupt handler to
if_link_state_change softint. The queue was protected by KERNEL_LOCK so far,
but if IFEF_MPSAFE is enabled, it becomes unsafe because (perhaps) an interrupt
handler of an interface with IFEF_MPSAFE doesn't take KERNEL_LOCK. Protect it
by a spin mutex.
Additionally with this change KERNEL_LOCK of if_link_state_change softint is
omitted if NET_MPSAFE is enabled.
Note that the spin mutex is now ifp->if_snd.ifq_lock as well as the case of
if_timer (see the comment).
if_timer, a counter used by if_watchdog (if_slowtimo), can be modified in
if_watchdog and if_start and/or interrupt handlers of some device drivers. All
such accesses were serialized by KERNEL_LOCK. If IFEF_MPSAFE is enabled,
KERNEL_LOCK of if_start (and perhaps interrupt handlers) is omitted and if_timer
becomes racy.
Fix the race condition by protecting if_timer by a spin mutex. if_watchdog_reset
and if_watchdog_stop are introduced to ensure to take the mutex on accessing
if_timer. Interface with IFEF_MPSAFE enabled must use the functions.
In addition, if_watchdog callout is now set CALLOUT_MPSAFE if IFEF_MPSAFE. It
means that if_watchdog implemented by a driver must be MP-safe if the driver is
set IFEF_MPSAFE.
Currenlty interfaces with IFEF_MPSAFE implementing if_watchdog and accessing
if_timer in if_start and interrupt handlers are only wm(4). wm is changed to
use the functions. (Its watchdog handler (wm_watchdog) is already MP-safe.
These contracts will be written somewhere in a further commit.
Note that the spin mutex is now ifp->if_snd.ifq_lock to avoid adding another
spin mutex to each interface. For now reusing it isn't problematic (see the
comment to know why) thought if that does matter in the future, feel free to
replace it with a new spin mutex. It's easy to do.
And ensure to turn off it before destruction as per IFF_RUNNING's description
"resource allocated". (The description is a bit doubtful though, I believe the
change is still proper.)
to netbsd:
- Check ETHERCAP_VLAN_HWTAGGING in ixgbe_setup_vlan_hw_support(). This change
has no influence to netbsd because it's enabled by default and NetBSD has
no API to disable it.
- Fix for netmap module.
- Remove never defined UDP_IPV4_EX
- Add SPDX-License-Identifier

1) RX may accesses freed area.
2) if_init() takes long time on many core machine.
Call ixgbe_jcl_reinit() not in ixgbe_setup_receive_ring() but in the
biginning of ixgbe_setup_receive_structures(). It was OK for pre multiqueue,
but it's not OK now because we support multiqueue.
- Fix comment of ixgbe_free_receive_ring().
- query the descriptor to get the interface version, needed to workaround
a bug in the BIOS/ACPI
- properly decode the event buffer in type/subtype, and handle multiple events
per handler call
- record some known type/subtype in a table, with associated actions.
