From f59ac0481660e66cec67f1d6b024e78b9dc715fe Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Fri, 29 Aug 2008 16:26:43 -0700 Subject: cfg80211: keep track of supported interface modes It is obviously good for userspace to know up front which interface modes a given piece of hardware might support (even if adding such an interface might fail later because of concurrency issues), so let's make cfg80211 aware of that. For good measure, disallow adding interfaces in all other modes so drivers don't forget to announce support for one mode when they add it.
