[OpenWrt-Devel] [PATCH] packages: fix airmon-ng output in multi bssid mode

[Tom Psyborg]

Create a patch that removes the output of unnecessary interface
informations which occur if the radio broadcasts more than one ssid to
speed up the operation and provide clean output. Also removes scanProcesses
function to get rid of the busybox output garbage.

Signed-off-by: Tomislav Požega <pozega.tomislav at gmail.com>

Removing the scanProcesses function should not affect the operations since
the function is intended for distributions that use external
network-managers and daemons. Same fix is required in CC branch.
