[PATCH 2/2] mac-sim: support creating radios with specific name.

[greearb@candelatech.com]

From: Ben Greear <greearb@candelatech.com>

Otherwise, it can be very difficult to know which is which
if you are trying to do detailed testing.

NOTE:  This depends on the earlier patch that added the radio-name
    attribute.
