Comment (by dyqith):
The code is very inconsistent between how different VAPs (AP, sta, wds,
monitor) handle the mode (802.11a/b/g) changes.
AP uses ieee80211_create_ibss(), but it won't create anything unless both
mode and channel are set.
STA uses ieee80211_check_scan(), using the mode as its limitation, it
scans on the channels of the given mode. (limited by athchans, but not by
the channel given by the user)
WDS and MONITOR is just put into RUN state without any modification, even
if mode and channels are set.
-----
Proposed changes:
1) The abg mode takes precedence over the channel choices.
2) STA should limit its scanning range to the current set channel, (bgscan
should take care of hopping otherwise)
3) WDS and MONITOR needs to be allowed to got into SCANNING state, thus
allowing them to change channel and modes
4) Scanning modules need to be created for WDS and MONITOR mode in order
for 3) to happen.
IMHO, any state should allow for a manual scan.
