count of the new bss node. The allocation
function gives us a reference. With this extra
reference, every invocation of reset_bss was
causing a leak of one node ~4kb every time the
interface was brought back up (or the BSS was reset
for other reasons).
This fixes ticket #1682. I can run ifconfig down/up
cycle for a long time. I'll run it overnight next
to be sure.

node in the node table. The node reference was
being taken in any path where the wds node was found
and not just when the wds node was first added.
This would have caused wds nodes to get inflated
reference counts, and be leaked on bss reset when
nodes were flushed from the node tables.

copy of the bss node is used to send a message
we need to make sure all code paths release
it when done. This bug combined with repeated
auth failures would cause node references to
grow with every failure. Then, if you were
taking down the interface and bringing it back
up you would leak one page (4kb) every time the
the node table was flushed on transition to UP.

This changes some iwpriv names, because I believe they will be more readily usable and understandable

HAL_INT_RX, HAL_INT_RXPHY, or HAL_INT_SWBA. In
such cases, we will collect the earliest hw tsf
sample we can get and this is passed into send_beacon
and the trigger processing helper functions.
This cuts the number of hardware TSF reads by a
factor of three per interrupt. We should be reading
the hardware TSF now once on interrupt entry, and
once in the second part of trigger processing when
we correct for hardware TSF rollover.

Move one hw tsf read into a conditional block as it is only used in a debug printout.
Replace one hw tsf read with a reference to the existing hw tsf in the buffer (which is more accurate anyway).

Since r3076 ath_tx_capture no longer exists, and ath_capture no longer frees the SKB because it was a confusing place to do that. The reverted changeset has been tested to cause leaks, and once reverted the code operates correctly.i

ath_tx_capture, for each frame in the list we have already freed the skb but the original pointer to
the list of skbs is still in bf->bf_skb. So when bf is returned with ath_return_txbuf it tries to
double-free, resuilting a spew of backtraces/warnings when reference debugging is enabled.
Not to mention the fact that the skb is double-freed.
