There are few places where ANI is started without checking
if it is right to start. This might lead to a case where ani
timer would be left undeleted and cause improper memory acccess
during module unload. This bug is clearly exposed with
paprd support where the driver detects tx hang and does a
chip reset. During this reset ani is (re)started without checking
if it needs to be started. This would leave a timer scheduled
even after all the resources are freed and cause a panic.

This patch introduces a bit in sc_flags to indicate if ani
needs to be started in sw_scan_start() and ath_reset().
This would fix the following panic. This issue is easily seen
with ar9003 + paprd.

We can wake all queues after a chip reset since everything should be set up and
we are ready to transmit. If we don't do that we might end up starting up with
stopped queues, not beeing able to transmit. (This started to happen after
"ath5k: clean up queue manipulation" but since periodic calibration also
stopped and started the queues this effect was hidden most of the time).

This way we can also get rid of the superfluous ath5k_reset_wake() function.

	ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose

Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(),
this may result in a rate scaling with wrong feedback (number
of unacked frames in this case). It is the last one in the chain
of buffers for an aggregate frame that should be checked.

Also it misses the initialization of this field in the buffer,
this may lead to a situation where we stop the sw retransmission
of failed subframes associated to this buffer.

We should use the same buffer size we set up for DMA also in the hardware
descriptor. Previously we used common->rx_bufsize for setting up the DMA
mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the
descriptor itself. The problem is that skb_tailroom(skb) can give us a larger
value than the size we set up for DMA before. This allows the hardware to write
into memory locations not set up for DMA. In practice this should rarely happen
because all packets should be smaller than the maximum 802.11 packet size.

On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559
bytes length (including padding for cache alignment) but sbk_tailroom() was
2592. Just consistently use rx_bufsize for all RX DMA memory sizes.

Also use the return value of the descriptor setup function.

Jumbo frames are not supported, and if they are seen it is likely
a bogus frame so just silently discard them instead of warning on
them all time. Also, instead of dropping them immediately though
move the check *after* we check for all sort of frame errors. This
should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.

Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be
happening.

This is reported quite often and if it fills the logs then this
needs to be addressed and to avoid spurious reports.

There are several places that use > ARRAY_SIZE() instead of
>= ARRAY_SIZE().
