[PATCH 01/14] tests: Add channels argument to run-all.sh and start.sh

From: Haim Dreyfuss <haim.dreyfuss at intel.com>

Add an option to run-all.sh and start.sh to get as an argument the
number of concurrent channels that mac80211_hwsim will be loaded with.
To start mac80211_hwsim with more than one channel, the following
parameter should be added to command line: channels=<num_channels>
The default is one channel (no concurrent channels).
The driver should be loaded with multi channel support in order to run
some tests.
