Do this per jail started, not per address. This will allow DAD to complete

trying to start before the IPv6 address was available to use and thus
erroring and failing to start.

When maxusers was unrestricted and maxfiles was allowed to autotune
much higher the result was that ncallout which was based on maxfiles
and maxproc grew much higher than was needed.
To fix this clip autotuning to the same number we would get with
the old maxusers algorithm which would stop scaling at 384
maxusers.
Growing ncalout higher is not likely to be needed since most consumers
of timeout(9) are gone and any higher value for ncallout causes the
callwheel hashes to be much larger than will even be needed for
most applications.

if_start().
This removes the overlapping data path TX from occuring, which
solves quite a number of the potential TX queue races in ath(4).
It doesn't fix the net80211 layer TX queue races and it doesn't
fix the raw TX path yet, but it's an important step towards this.
This hasn't dropped the TX performance in my testing; primarily
because now the TX path can quickly queue frames and continue
along processing.
This involves a few rather deep changes:
* Use the ath_buf as a queue placeholder for now, as we need to be
able to support queuing a list of mbufs (ie, when transmitting
fragments) and m_nextpkt can't be used here (because it's what is
joining the fragments together)
* if_transmit() now simply allocates the ath_buf and queues it to
a driver TX staging queue.
* TX is now moved into a taskqueue function.
* The TX taskqueue function now dequeues and transmits frames.
* Fragments are handled correctly here - as the current API passes
the fragment list as one mbuf list (joined with m_nextpkt) through
to the driver if_transmit().
* For the couple of places where ath_start() may be called (mostly
from net80211 when starting the VAP up again), just reimplement
it using the new enqueue and taskqueue methods.
What I don't like (about this work and the TX code in general):
* I'm using the same lock for the staging TX queue management and the
actual TX. This isn't required; I'm just being slack.
* I haven't yet moved TX to a separate taskqueue (but the taskqueue is
created); it's easy enough to do this later if necessary. I just need
to make sure it's a higher priority queue, so TX has the same
behaviour as it used to (where it would preempt existing RX..)
* I need to re-review the TX path a little more and make sure that
ieee80211_node_*() functions aren't called within the TX lock.
When queueing, I should just push failed frames into a queue and
when I'm wrapping up the TX code, unlock the TX lock and
call ieee80211_node_free() on each.
* It would be nice if I could hold the TX lock for the entire
TX and TX completion, rather than this release/re-acquire behaviour.
But that requires that I shuffle around the TX completion code
to handle actual ath_buf free and net80211 callback/free outside
of the TX lock. That's one of my next projects.
* the ic_raw_xmit() path doesn't use this yet - so it still has
sequencing problems with parallel, overlapping calls to the
data path. I'll fix this later.
Tested:
* Hostap - AR9280, AR9220
* STA - AR5212, AR9280, AR5416
save queue code.
Instead, use if_transmit() directly - and handle the cases where frame
transmission fails.
I don't necessarily like this and I think at this point the M_ENCAP check,
node freeing upon fail and the actual if_transmit() call should be done
in methods in ieee80211_freebsd.c, but I digress slightly..
This removes one of the last few uses of if_start() and the ifnet
if_snd queue. The last major offender is ieee80211_output.c, where
ieee80211_start() implements if_start() and uses the ifnet queue
directly.
(There's a couple of gotchas here, where the if_start pointer is
compared to ieee80211_start(), but that's a later problem.)
CISS_MAX_LOGICAL to 107
Submitter wanted to increase the number of logical disks supported by ciss(4)
by simply raising the CISS_MAX_LOGICAL value even higher. Instead, consult
the documentation for the raid controller (OPENCISS) and poke the controller
bits to ask it for how many logical/physical disks it can handle.
Revert svn R242089 that raised CISS_MAX_LOGICAL to 64 for all controllers.
For older controllers that don't support this mechanism, fallback to the old
value of 16 logical disks. Tested on P420, P410, P400 and 6i model ciss(4)
controllers.
This should will be MFC'd back to stable/9 stable/8 and stable/7 after the MFC
period.
