From: Ben Greear Date: Wed, 22 Oct 2014 19:23:03 +0000 (-0700) Subject: mac80211: support creating wiphy w/out creating wlanX X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e27513fbd030d8558cfa9250bd62b2baf19dc114;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mac80211: support creating wiphy w/out creating wlanX This will be helpful when using the mac80211_hwsim wiphys and automated testing. Let user create the vifs as needed, and named as expected.
