Setting tid information in the TX header is required only for QoS
frames. Not handling this case causes severe data loss with some APs.

ath9k_hw_setmac() only copies the mac address it is called with into
common->macaddr, yet in all call sites, the supplied mac address pointer
is already common->macaddr.

The new ANI implementation will use this to skip ANI
calibration upon a scan. This cannot be ported to the
older ANI implementation unless default ANI values from
the ANI are also used upon a scan. This is essentially
what one of the things thenew ANI does.

There is no need to determine the HW queue
for each packet that is transmitted. The endpoint
can be chosen directly based on the queue type
that mac80211 sends down.

This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
It also does not remove null void functions with return.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'
with some cleanups by hand.
Compile tested x86 allmodconfig only.

A bunch of validation and processing in the RX IRQ handler
can be moved to the RX tasklet. The IRQ handler is
already heavy, with the memory allocation for handling
stream mode. Also, a memcpy of 40 bytes for every packet
can be avoided in the handler.

Check for the endpoint IDs when processing
TX completions and drop the unsupported EPIDs.
We can add other endpoints (UAPSD,..) when support
is added.

Set IEEE80211_HW_RX_INCLUDES_FCS to indicate that
the FCS is present in RX frames. Also, remove a redundant
assignment of skb length and include the FCS_LEN
when checking padding.
Fixing this issue makes TKIP work.

Accessing the sta pointer in TX completion without
approprate RCU protection is wrong. Fix this.
Also, RCU protection is needed when the station's
aggregation state is updated. Handle this properly.

The calculation of RX filter is fairly different
between ath9k and ath9k_htc, trying to make this
common between the two drivers would result in code churn.
While at it, remove the handling of PSPOLL filter,
it can be added when(if) AP support is added to ath9k_htc.
