From d82121845d44334f5ec3c98906d1e4a592350beb Mon Sep 17 00:00:00 2001 From: Aviya Erenfeld Date: Mon, 29 Aug 2016 23:25:15 +0300 Subject: [PATCH] mac80211: refactor monitor representation in sdata Insert the u32 monitor flags variable in a new structure that represents a monitor interface. This will allow to add more configuration variables to that structure which will happen in an upcoming change.
