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.
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.
- 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.

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.

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.
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.
This code initializes the GMAC clock and sets the pin mux to rgmii.
It also override the if_dwc defaults to set the alternate descriptor type
and MII clock used on A20.
Tested on cubieboard2 and banana pi.
