ca85b7c4e9 Synchronize mode pages between HA peers.
We allow to modify only few fields in mode pages now, but still it is
not good if they unexpectedly change during failover.  Also this fixes
reporting of "Mode parameters changed" UAs on secondary node.

a85700a912 Make HA peers announce their parameters on connect.
HA protocol requires strict version, parameters and configuration match.
Differences there may cause full set of problems up to kernel panic.
To avoid that, validate peer parameters on connect, and abort connection
immediately if some mismatch detected.

8264830c95 Some refactoring of the buf/vm interface.
- Eliminate bogus page replacement that is inconsistently applied in the
   invalidation loop in brelse.  This has been a no-op in modern times as
   biodone() is responsible for cleaning up after bogus pages.  This
   would've spammed the console with printfs at a minimum.
 - Allow the compiler and human readers alike to reason about allocbuf()
   by splitting it into constituent parts.
 - Separate the VM manipulating and buf manipulating code in brelse() and
   bufdone() so that the intentions are clear.  This makes it evident that
   there are several duplicated buf pages loops that will be consolidated
   at a later time.

37864a5451 Call ast when handling irq from userspace, otherwise we could miss

action, so the impact is not serious.

Remove duplicated interrupt disable in restore_registers macro, when

1f57d8c66b Ensure that maxproc does not exceed pid_max, at the time of boot.
Changes to kern.pid_max mib after the boot can break this relation.

The maxfiles value was calculated by the MAXFILES formula based on
maxproc value, but this change decouples them, and MAXFILES now
references maxusers.  Without manual tuning, the maxfiles default
value remains as it was prior to this commit.  But for systems which
have tuned maxproc and rely on maxfiles to adjust, additional
reconfiguration is needed.

b1ce89f2bc In the UDP over IPv6 implementation several cases are using the wrong protocol,

the upper layer protocol), or using hard-coded UDP instead of UDP or UDP-Lite
possibly switching protocols.  Fix those cases for UDP-Lite to work correctly.

77435f1835 Convert if_rsu to use a deferred transmit task rather than using rsu_start()
to do it directly.

Ensure that we re-queue starting transmit upon TX completion.

This solves two issues:

* It stops tx stalls - before this, if the transmit path filled the
  mbuf queue then it'd never start another transmit.

* It enforces ordering - this is very required for 802.11n which
  requires frames to be transmitted in the order they're queued.
  Since everything remotely involved in USB has an unlock/thing/relock
  pattern with that mutex, the only way to guarantee TX ordering is
  to 100% defer it into a separate thread.

This now survives an iperf test and gets a reliable 30mbit/sec.

829e0b0b84 Drain the mbuf queue upon rsu_stop().
Correctly (I hope!) remove net80211 references before doing so.
Just doing a dumb mbufq drain isn't enough.

If enough traffic occurs and the mbuf queue fills up then transmit
stalls (which I'm not fixing in this commit!) but then the mbuf queue
stays full until the driver is removed.  There's also the net80211
node refcounting leak.

This just ensures that during rsu_stop and detach the mbuf queue
is purged (and references!) so the queue-full situation can be
recovered from.
