From b207cdb07f3f01ec1adaac62e9d0cc918c60a81a Mon Sep 17 00:00:00 2001 From: Alexander Bondar Date: Sat, 22 Dec 2012 10:43:33 +0200 Subject: mac80211: add vif debugfs driver callbacks Add debugfs driver callbacks so drivers can add debugfs entries for interfaces. Note that they _must_ remove the entries again as add/remove in the driver doesn't correspond to add/remove in debugfs; the former is up/down while the latter is netdev create/destroy.
