Subject: Pass our currently configured SSID to iwm(4) scan commands.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=0dfa4009674e3444e346b13939fa4d22eb92befe;p=openbsd

Pass our currently configured SSID to iwm(4) scan commands.

This makes connecting to silly "hidden" networks work, which was a long
standing problem with iwm(4). My past observations where other SSIDs were
filtered from scan results while associated can no longer be reproduced.
