We need to be able to test some more restart behavior that depends on
knowing specifically where we're at (inside the event loop or outside of
the event loop). Truncate the pidfile until the process is restarted to
give the test a clean marker rather than having to add arbitrary delays
and hoping for the best.

In vfp_save_state_savectx we check if the pcb has a NULL vfp state.
When it's called multiple times with the same pcb then we can panic
because the vfp state has been set.
Weaken the requirement for the state pointer to be NULL by also
allowing it to point to the pcb vfp state area we are about to use.

When multiple IRQs are specified in a single resource then we only
check the first. Change this to check all interrupts for the value
we expect to find.
Without this we may still enable the interrupt, but it can have the
wrong polatiry or trigger. This can cause an interrupt storm if the
interrupt was configured with a level trigger when it should have
been an edge.

The driver wasn't stable - it would start fine, but during scan
it would eventually hang and no further command endpoint transfers
would complete.
After adding some debugging and looking at the logs I noticed that
things went sideways once a /data/ frame was sent. The channel
change config happened between the data frame being sent and
being completed.
My guess is that the firmware doesn't like a channel change
and reset whilst there's pending data frames. Checking the Linux
driver I found that it was doing a flush before a channel change,
and we're doing it afterwards. This acts like a fence around
ensuring scheduled TX work has completed. In net80211 the
transmit path and the control path aren't serialised, so it's
very often the case that ioctls, state changes, etc occur
whilst in parallel there are frame transmits being scheduled.
This seems to happen more frequently on a more recent, high core
(8) machine with XHCI. I remember testing this driver years ago
on single and dual core CPU laptops with no problems.
So, add some flushes - before a channel change, and during
a transition to AUTH when the BSS config is being programmed into
the firmware. These two fences seem enough to reliably
associate as a 2GHz and 5GHz STA.
Note that this isn't entirely blocking all newly queued
transmit work from occuring until after the NIC has finished
configuration. That will need some further investigation.

* Wistron NuWeb AR5523 dual-band NIC, STA mode, 2/5GHz

Use the correct ID, as I have one of these NICs.
Add the previous one back in case it's out there in the wild.
@emaste did a bit of a dig into the product numbers.
@sam did change the ID from 0x0828 -> 082a in a commit
a long while back. It's worth reading the code review for
further details.
However, I do have one of these NICs and I verified that
it indeed has the given ID, and with some follow-up work
to fix some race conditions, it works fine in 2GHz 11bg
and 5GHz 11a operation.

This will be useful when fixing up the sequence number generation
and checks, as the rules around how sequence numbers are generated
have been clarified in 802.11-2016 and later. QoS-NULL frames are
explicitly marked as "any sequence number".
But for now, just create a macro and use it in the one place
it's currently being used as a check - ath(4).
* Add IEEE80211_IS_QOS_NULL().
* Change the "will this frame go into the TX block-ack window" check
in the ath(4) transmit path. Note this changes the check to be
more specific, but both paths already had previous checks to ensure
they're QoS data frames.

pflow opens sockets in the kernel to transmit netflow information.

Install a callback on the PR_METHOD_REMOVE jail callback and close the sockets
there. This ensures that the jail can get cleaned up.
