Comment (by dyqith):
New comment (relating to ticket:275, ticket:228):
(abg) mode changes, channel changes and scanning are all inter-related.
Classifying information by VAP operation:
STA/managed::
An STA has no concept of a fixed channel when its not assoc/auth
because of its SCAN_STATE.
In the SCAN_STATE, the STA jumps from channel to channel (channels set
by athchans)
What everyone was hoping for was this (i think): When we put "iwconfig
ath0 channel 10", the sta will stop jumping channels, and stick with the
one given (correct ?)
Another thing is the way scanning is not getting cancelled when another
call is coming in. Cancelling the scan may not be appropriate (i.e. One
program asks for a scan, another asks for a scan afterwards, should the
second cancel the firsts scan ? I would think not)
AP/master::
Changing channel/mode is fine (except when channel is set to something
other than 0 and then mode can't be changed from a to b/g).
Scanning is not supported by AP (even though a wlan_scan_ap is present)
monitor/wds::
Channel/mode changes are not happening because these are not AP nor
STA. They do not call create_ibss() or jump channels when SCANNING. These
do not have a SCANNING state (gets put into RUN). To help put them into a
correct channel/mode, new code must be placed to force them as such
(ticket:612), but must also force all VAPs to change like any other code.
adhoc/ahdemo::
Haven't looked into it, someone want to provide something for it ?
