4245d31347 ath9k: do not insert padding into tx buffers on AR9380+
With the new EDMA descriptor format, a single descriptor can contain up
to four buffer pointers. By splitting the buffer into two parts, we can
let the hardware add the padding internally instead of using memmove on
the skb data.

3afd21e7c5 ath9k: optimize ath_tx_rc_status usage
The only flag that needs to be set when ath_tx_rc_status is called with
rc_update == false is the IEEE80211_TX_STAT_TX_FILTERED flag. All other
data is ignored in that case.
This flag can be set from ath_tx_complete_buf instead, so that we can
drop a few redundant calls to ath_tx_rc_status and remove the rc_update
function parameter

55768fa6d9 libertas: prioritize usb8388_olpc.bin firmware on OLPC machines
Normally, the v9 firmware will be loaded if it's available.  However, on
OLPC XO-1 machines, the olpc-specific firmware supports extra functionality.
This makes the libertas driver attempt to load the custom firmware first
if the machine is an OLPC machine; if that fails (or it's not an OLPC
machine), fall back to attempting to load the other firmwares.

usb8388_olpc.bin is currently found in the linux-firmware repository.

a2b1328a23 rt2x00: Make use of sta_add/remove callbacks in rt2800
This allows us to assign a WCID to each STA even for STAs without
crypto key.

To achieve this search for an unused WCID in the HW WCID table and
assign it to the according STA. When configuring a pairwise key for this
STA we don't need to write the MAC address and BSSIDX anymore but just
update the crypto related fields in the WCID_ATTR table.

This has two advantages:

1) Setting a new key for an already available STA (PTK rekeying) is
slightly less expensive and should improve performance in situations
where a lot of rekeying happens (e.g. a huge number of stations and/or
a small rekeying interval)

2) The TXWI now gets a WCID assigned for unencrypted frames which will
be reflected in the corresponding tx status report. This should make tx
status reports in unencrypted AP mode more reliable as we can
distinguish between multiple key-less STAs.
