Yeah, that's probably appropriate, otherwise just 'iwconfig eth1 channel
6' would trigger association to _something_, which is wrong. Changing
the channel should (and does) trigger reassociation, but only if there
is an SSID to associate with!
In plain english, this if statement should read:
"If associate=0, and no locked SSID or locked BSSID have been set, don't
associate"

wpa_supplicant sets (or doesn't set) the channel, not NM...
Care to submit a patch with the appropriate signed-off-by tag?
Thanks!
