[update]
thought it was fixed in latest commit (1391d154092f9e0e7702086ab9af1558584cc694) , but unfortunately I still get it:

switch to channel 12
scandone
-> wifi_scan_done_cb(3fff68d8, 1)

and then wireless connection is disconnected

...but it appears to go away if I patch cnx_csa_fn() to do nothing:

40217830 <cnx_csa_fn>:
40217830: f00d ret.n

actually it works better than patching ieee80211_add_csa() since it doesn't react to CSA's while scanning instead of not sending CSA's (I guess).

What is cnx_csa_fn() supposed to do anyway?
