This started showing up when doing lots of aggregate traffic. For TDMA it's
always no-ACK traffic and I didn't notice this, and I didn't notice it
when doing 11abg traffic as it didn't fail enough in a bad way to trigger
this.
This showed up as the fifo depth being < 0.
Eg:
Jun 19 09:23:07 gertrude kernel: ath0: ath_tx_edma_push_staging_list: queued 2 packets; depth=2, fifo depth=1
Jun 19 09:23:07 gertrude kernel: ath0: ath_edma_tx_processq: Q1, bf=0xfffffe000385f068, start=1, end=1
Jun 19 09:23:07 gertrude kernel: ath0: ath_edma_tx_processq: Q1: FIFO depth is now 0 (1)
Jun 19 09:23:07 gertrude kernel: ath0: ath_edma_tx_processq: Q1, bf=0xfffffe0003866fe8, start=0, end=1
Jun 19 09:23:07 gertrude kernel: ath0: ath_edma_tx_processq: Q1: FIFO depth is now -1 (0)
So, clear the flags before adding them to a TX queue, so if they're
re-added for the retransmit path it'll clear whatever they were and
not double-account the FIFOEND flag. Oops.

Drop scan generation number and node table scan lock - the only place
where ni_scangen is checked is in ieee80211_timeout_stations() (and it
is used to prevent duplicate checking of the same node); node scan lock
protects only this variable + node table scan generation number.
This will fix (at least) next LOR (hostap mode):

In addition to the above:
* switch to ieee80211_iterate_nodes();
* do not assert that node table lock is held, while calling node_age();
that's not really needed (there are no resources, which can be protected
by this lock) + this fixes LOR/deadlock between ieee80211_timeout_stations()
and ieee80211_set_tim() (easy to reproduce in HOSTAP mode while
sending something to an STA with enabled power management).

* (adrian) AR9380, STA mode
* (adrian) AR9380, AR9331, AR9580, hostap mode

It turns out the frame scheduling policies (eg DBA_GATED) operate on
a single TX FIFO entry. ASAP scheduling is fine; those frames always
go out.
DBA-gated sets the TX queue ready when the DBA timer fires, which triggers
a beacon transmit. Normally this is used for content-after-beacon queue
(CABQ) work, which needs to burst out immediately after a beacon.
(eg broadcast, multicast, etc frames.) This is a general policy that you
can use for any queue, and Sam's TDMA code uses it.
When DBA_GATED is used and something like say, an 11e TX burst window,
it only operates on a single TX FIFO entry. If you have a single frame
per TX FIFO entry and say, a 2.5ms long burst window (eg TDMA!) then it'll
only burst a single frame every 2.5ms. If there's no gating (eg ASAP) then
the burst window is fine, and multiple TX FIFO slots get used.
The CABQ code does pack in a list of frames (ie, the whole cabq) but
up until this commit, the normal TX queues didn't. It showed up when
I started to debug TDMA on the AR9380 and later.
This commit doesn't fix the TDMA case - that's still broken here, because
all I'm doing here is allowing 'some' frames to be bursting, but I'm
certainly not filling the whole TX FIFO slot entry with frames.
Doing that 'properly' kind of requires me to take into account how long
packets should take to transmit and say, doing 1.5 or something times that
per TX FIFO slot, as if you partially transmit a slot, when it's next
gated it'll just finish that TX FIFO slot, then not advance to the next
one.
Now, I /also/ think queuing a new packet restarts DMA, but you have to
push new frames into the TX FIFO. I need to experiment some more with
this because if it's really the case, I will be able to do TDMA support
without the egregious hacks I have in my local tree. Sam's TDMA code
for previous chips would just kick the TXE bit to push along DMA
again, but we can't do that for EDMA chips - we /have/ to push a new
frame into the TX FIFO to restart DMA. Ugh.

There is no reason to return non-zero value from zfs_probe_partition()
as that causes following partitions to not be probed for ZFS vdevs.
A particular scenario that I encountered is a GPT partitioned disk
where several partitions have freebsd-zfs type. A partition with a lower
index is used as a cache (l2arc) vdev and in that case case zfs_probe()
returned a non-zero status. That status was returned to ptable_iterate()
and caused it to abort the iteration. Because of that the subsequent
partitions were not probed and a root pool was not discovered resulting
in a boot failure.
While there fix the style for nearby return statements.

- This was broken by r300350 and r300885.
- Add some comments around the external GCC logic since it is spread out
and in need of some cleanup.
- The problem was that X_COMPILER_TYPE is always defined from CC->XCC's
default, so if /usr/bin/cc is GCC (as it is on native powerpc64) then
X_COMPILER_TYPE was getting GCC and triggering the external logic in
Makefile.libcompat. It was intended to always provide -isystem with
GCC since --sysroot is used into the lib32 sysroot which won't modify
the header path without the -isystem. The use of the libc++/std=c++11
override was only intended to be used for external compilers though
(more accurately GCC 4.8+ but that's a separate assumption to
cleanup). Apply the same logic from Makefile.inc1 to Makefile.libcompat
to only add the libc++ override when needed for external compilers.
