The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code
to only report key miss errors if a MIC error wasn't reported.
When checking the flags in that order in the MAC code, it might miss some
real events, because the value of the MIC error flag is undefined under
some conditions.
The primary issue addressed by the previous commit is making sure that
MIC errors are properly reported on the STA side. This can be fixed in
a better way by adding a separate rx status flag for key miss and
ignoring it for multicast frames.
This fix slightly improves stability in AP mode on some older hardware,
like AR9132.

The code for handling various restrictions concerning regulatory limits,
antenna gain, etc. is very convoluted and duplicated across various
EEPROM parsing implementations, making it hard to review.
This patch partially cleans up the mess by unifying regulatory limit
handling in one function and simplifying handling of antenna gain.
It also removes unused transmit power scaling arrays from the EEPROM code,
which belonged to an unimplemented API that isn't supposed to be in
the driver anyway.

PHY errors relevant for ANI are always tracked by hardware counters, the
bits that allow them to pass through the rx filter are independent of that.
Enabling PHY errors in the rx filter often creates lots of useless DMA traffic
and might be responsible for some of the rx dma stop failure warnings.

This was another workaround for truesize "bugs".
The reason we did this was that when we orphaned
the SKB it wouldn't be truesize-checked later.
Now that the check is gone (and we just charge
the former smaller size to the socket) there's
no longer a reason to orphan the skb here.
Keep the skb charged to the socket until it is
really freed (or orphaned in TX status). This
helps flow control and allows us to get at the
socket later for other purposes.

There's no need to adjust truesize.
The history of this was that we always ran into
skb_truesize_bug (via skb_truesize_check) which
has since been removed in commit 92a0acce18.
skb_truesize_check() checked that truesize was
bigger or equal to the actual allocation, which
would trigger in mac80211 due to header adding.
The check no longer exists and we shouldn't be
messing with the truesize anwyay.

1) by moving it out of tx_data.flags, we can in

not doing fragmentation may be honoured

th5k_hw_setup_tx_queue() returns a valid offset into the ah->ah_txq[]

Both have AR5K_NUM_TX_QUEUES elements. So this error handling code
will never trigger.
Also it's wrong. The call to ath5k_hw_release_tx_queue() with a qnum
of AR5K_NUM_TX_QUEUES or more will just trigger a WARN_ON() and
return. Or if it missed the WARN_ON(), it would just corrupt some

In browsers that access dynamic underlying data structures, like in the

reference to the underlying data structure, because they can have gone
away, decayed.
This fixes a problem where after a while the top entries get behind the
top of the screen, i.e. the top_idx stays at 0, which means it is at the
first entry in the rb_tree when in fact it wasn't because the
browser->top didn't got revalidated after the timer ran and the
underlying data structure got updated.
