a non-loss reset.
When the drain functions are called, the holding descriptor and link pointers
are NULLed out.
But when the processq function is called during a non-loss reset, this
doesn't occur. So the next time a DMA occurs, it's chained to a descriptor
that no longer exists and the hardware gets angry.
Tested:
* AR5416, STA mode; use sysctl dev.ath.X.forcebstuck=1 to force a non-loss
reset.
TODO:
* Further AR9380 testing just to check that the behaviour for the EDMA
chips is sane.

The "blessed" way here is to take a node reference before referencing
anything inside the node, otherwise the node can be freed between
the time the pointer is copied/dereferenced and the time the node contents
are used.
This mirrors fixes that I've done elsewhere in the net80211/driver

assigned conflicting ranges to BARs then leaving the BARs alone could
result in one device stealing mmio accesses intended to go to a second
device. Prior to 233677 the PCI bus driver attempted to handle this case
by clearing the BAR to 0 depending on BARs based at 0 not decoding (which
is not guaranteed to be true). Now when a conflicting BAR is detected the
following steps are taken:
1) If hw.pci.realloc_bars (a new tunable) is enabled (default is enabled),
then ignore the current BAR setting from the firmware and attempt to
allocate a fresh resource range for the BAR.
2) If 1) failed (or was disabled), disable decoding for the relevant
BAR type (e.g. disable mem decoding for a memory BAR) and emit a
warning if booting verbose.

all requested data was sent. The reason is that xfsize <= 0 condition
must not be tested at all if space == loopbytes. Otherwise, the done

Instead of moving the condition to exiting the inner loop after the
xfersize check, directly check for the completed transfer before the
testing of the available space in the socket buffer, and revert item 1
of r248830. It is arguably another bug to sleep waiting for socket
buffer space (or return EAGAIN for non-blocking socket) if all bytes

Section 3 (Library Functions) looks wrong for this manual page, which
contains only module description, that is why initially it was located
to section 8 (System Manager's Manual). On the other hand manual
pages for all other bsnmpd modules are already located in the section
3, and having all pages in one section looks more consistent. Also,
currently, similarly to manuals for other modules, snmp_hast manual

Flip back on the "always continue TX DMA using the holding descriptor"
code - by always setting ATH_BUF_BUSY and never setting axq_link to NULL.
Since the holding descriptor is accessed via txq->axq_link and _that_
is done behind the TXQ lock rather than the TX path lock, the holding
descriptor stuff itself needs to be behind the TXQ lock.
So, do the mental gymnastics needed to do this.
I've not seen any of the hardware failures that I was seeing when
I last tried to do this.
