[PATCH] hwsim tests: create new radios for MCC tests

Johannes Berg johannes at sipsolutions.net
Thu Nov 27 11:05:20 EST 2014


From: Johannes Berg <johannes.berg at intel.com>

For tests that require a radio with multi-channel concurrency,
create a new one on the fly that does have more than 1 channel.
