mac80211: resume properly, add suspend/resume test
When mac80211 resumes, it currently doesn't reconfigure the interfaces entirely and also doesn't reconfigure BSS information -- fix this. Also, to be able to test this, add a debugfs file that just calls the suspend/resume code to see what happens when we go through that, without needing the time-consuming suspend/resume cycle. (Original version broke the build for CONFIG_PM=n. Define alternative functions for that situation. -- JWL) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
