Transmit power level in a channel is determined based on the dfs region.
To support regulatory rules dfs region should be configured to device during
set channel request. Also antenna gain values are taken from the mac80211
channel parameters instead of fixed values.

TX power can be configured from iwconfig, iw or from mac80211 when
regulatory changes are done. Hence support for configuring tx power
to device is added using the RADIO_PARAMS_UPDATE command frame.

Filtering rx frames after connection in station mode avoids the
overhead of processing un-necessary frames. Hence rx filter frame
is added which can be configured to device at suitable times.

* Command frame vap_capabilites is modified to use for vap add, vap delete
and vap update in firmware, hence new filed vap status is added.
* When interface is down this frame needs to be send with vap status delete.
Otherwise it is considered as wrong frame for the same interface in firmware.
* vap_update status is reserved for future.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

use true and false thus bool tests don't need an explicit comparison.

Fix a potential memory leak in the error path of function
rsi_send_auto_rate_request(). In case memory allocation for array
'selected_rates' fails, the error path exits and leaves the previously

Fix a potential memory leak in function rsi_set_channel() that is used to
program channel changes. The channel check block for the frequency bands
directly exits the function in case of an error, thus leaving an already
allocated skb unreferenced. Move the checks above allocating the skb.
