It turns out that the V4K eeprom definitions (used by the AR9285 and
its derivatives) is wrong. These values are at least causing issues
on my AR2427.
With this fix (and initvals in a subsequent commit), the AR2427 behaves
a lot better.
Note - there's still significant drift between the ath9k v4k eeprom
init code (again, used by AR9285 and derivatives) and what's in this
tree. That needs to be investigated and resolved.
Khelp/Hhook KPIs to hook into the TCP stack and maintain a per-connection, low
noise estimate of the instantaneous RTT. ERTT's implementation is robust even in
the face of delayed acknowledgements and/or TSO being in use for a connection.
A high quality, low noise RTT estimate is a requirement for applications such as
delay-based congestion control, for which we will be importing some algorithm
implementations shortly.

changed, knowing that uart_tty_outwakeup() will do the right

The linux ath9k driver and (from what I've been told) the atheros reference
driver does this; it then leaves discarding 11n frames to the 802.11 layer.
Whilst I'm here, merge in a fix from ath9k which maintains a turbo register
setting when enabling the 11n register; and remove an un-needed (duplicate)
flag setting.
It does not make sense to shut down daemons that were not started. In
particular, this fixes loss of mixer settings when shutting down using
shutdown(8), init(8) or ctrl+alt+del from single-user mode.
If /etc/rc reboots, /etc/rc.shutdown is not run.
Also fix segfaults and other erratic behaviour if init receives SIGHUP or
SIGTSTP while in single-user mode.
This commit does not attempt to fix any badness with signal handlers

condition). I believe it does not make this badness any worse.

write to the buffer causes it to overflow. We therefore can't hold the CC list
rwlock over a call to sbuf_printf() for an sbuf configured with SBUF_AUTOEXTEND.
Switch to a fixed length sbuf which should be of sufficient size except in the
very unlikely event that the sysctl is being processed as one or more new
algorithms are loaded. If that happens, we accept the race and may fail the
sysctl gracefully if there is insufficient room to print the names of all the
algorithms.
This should address a WITNESS warning and the potential panic that would occur
if the sbuf call to malloc did sleep whilst holding the CC list rwlock.

Fix a long standing bug, where the procs ticks where assumed to be in
us. Instead, read cpu_tick_frequency from the kernel and use the same
logic to convert runtime. This is still too optimistic in that it
assumes cpu_tick_frequency is available and fixed. Since this function
is only called on crashdumps, I think we can live with that. Testing has
shown the values to be correct for different kern.hz inside Virtualbox.
