The users of the fwil put an error message in the log so there is
no need to do the same in the lower level functions in fwil when
the firmware on the device returns an error. Some errors can be
ignored for the driver to function and this will avoid driver users
to point at the low-level error message as potential bug.

Applying ++ to a bool is equivalent to setting it true, regardless of
its initial value (bools are not uint1_t). Hence the function
wl_get_vif_state_all can only ever return true/false. The only in-tree
caller uses its return value as a boolean. So update its return type,
and since the list traversal and bit testing have no side effects,
just return true immediately. Its return value tells if any vif is in
the specified state, so also rename it to brcmf_get_vif_state_any.

Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.

This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).

As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the

If BT is active, we need to refrain from using the shared

link quality tables. But for management frames, the rate is
written in the Tx command by the driver.
Hence the driver needs to make sure not use the shared
antenna when BT is active for any frames that don't use
the rate scale table such as management frames or multicast.
