Hi Jean,
A query regarding wireless events: under which circumstances should a
driver/stack send a SIOCGIWSCAN event to userspace?
Should it be sent whenever a driver has new scan results available, or
only when the user requested a scan a short time beforehand (via
SIOCSIWSCAN)?
I ask this because softmac is sending the SIOCGIWSCAN event even when
the user did not explicitly ask for it.
For example, the user sets an essid. softmac starts a scan in order to
find the requested network. The network is found, the scan completes,
and softmac sends SIOCGIWSCAN. softmac then authenticates to that
network, associates, and then sends SIOCGIWAP.
I think the 'extra' SIOCGIWSCAN event may be confusing wpa_supplicant
(but have not confirmed that yet).
Thanks,
Daniel
