[PATCH] auto-t: scan as many times as needed to find networks

[PATCH] auto-t: scan as many times as needed to find networks

[James Prestwood]

Certain autotests coupled with slower test machines can result in lost
beacons and "Network not found" errors. In attempt to help with this
the test can just rescan (30 seconds max) until the network is found.
