Subject: iwlwifi: define the non shared antenna per hardware
X-Git-Tag: firefly_0821_release~176^2~3001^2~75^2~134^2~14
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=bbab758279a14556e6ccb17b1f98935634eeb8d5;p=firefly-linux-kernel-4.4.55.git

iwlwifi: define the non shared antenna per hardware

The sharing model will differ in new hardware. Define the
non shared antenna based on the device so that different
devices can have different names for the non shared antenna.
