Currently iwlwifi will eventually exhaust the station
table when adding the BSSID station for IBSS mode,
unless the interface is set down.

The new mac80211 ibss joined/left notification allows
us to fix that easily by moving the code to add the
IBSS station to the notification, and also adding
code to remove it again when we leave the IBSS.

iwl3945 should not use iwl_add_local_station(..., false)
because that would leave the IWL_STA_UCODE_INPROGRESS flag
set for the station, which is not desirable. Instead it
can use iwl3945_add_bcast_station() here.

When adding the broadcast station the link quality command is
generated on demand, sent to device, and disappears. It is thus not
available for later cases when we need to restore stations and need
to send the link quality command afterwards. Now, when first adding the
broadcast station, also generate its link quality command to always be
available for later restoring.

Also fix an issue when adding local stations where the "in progress" state
is never cleared.

All of the driver's kick_tx_queue callback functions treat the TX queue

got an error about "No suitable DMA available" followed by an error
that no device could be detected. When comparing the rtl8180 driver to

the custom mask to DMA_BIT_MASK(32) which fixed my issue."

rt2800 devices use a different enumeration to specify what IFS values should
be used on frame transmission compared to the other rt2x00 devices. Hence,
create a new enum called txop that contains the valid values.

Furthermore use the appropriate txop values as found in the ralink drivers:
- TXOP_BACKOFF for management frames
- TXOP_SIFS for subsequent fragments in a burst
- TXOP_HTTXOP for all data frames

This patch changes the way JOIN's are performed, and channel numbers updated.
The reason for this is that the firmware JOIN command clears WPA(2) key
material, and if done while associated to a WPA(2) secured AP, will render
the data-path unusable.

While the channel is not usually changed while associated (and currently we
could not even support something like that), after performing a scan operation
while associated, mac80211 will re-set the current channel to the driver. This
caused our problem.

Also, the mac80211 is assuming that the driver channel configuration remains
persistent over periods of IDLE. Therefore remove channel resetting to zero
from the unjoin function.
