Helmut Schaa ead2bb64a3 rt2x00: Add WCID to HT TX descriptor
When sending an unencrypted frame to a STA the driver might want to pass
a suitable WCID since we don't have a key index to allow tx status
reports to get properly assigned to the correct STA.

Helmut Schaa f03fcfc110 rt2x00: Add WCID to crypto struct
When a WCID was already assigned to a STA the key configuration
functions need to use the same WCID for configuring the keys. Hence, add
the WCID to the crypo configuration structure.

Helmut Schaa b4943d8113 rt2x00: Introduce sta_add/remove callbacks
This implements a basic sta_add and sta_remove callback. Introduce a new
structure rt2x00_sta and ask mac80211 to allocate it as private part of
its ieee80211_sta. rt2x00_sta only contains the WCID for now.

The sta_add callback allows the driver to assign a WCID to a station
that is currently being added. The same wcid is also passed to the
sta_remove callback one mac80211 removes this STA.

Helmut Schaa 550245b56c rt2x00: Remove incorrect led blink
rt2800 devices are not capable of configuring arbitrary LED on/off
periods. The LED_CFG register fields ON_PERIOD and OFF_PERIOD are only
used by the hw when the LED mode is set to "blink upon TX".

Hence, remove the blink callback. This will result in software emulation
for LED blinking.
