This patch adds a configuration option to mac80211 that lets you
enable or disable the debugfs internal state export.
I intentionally made this option not depend on MAC80211_DEBUG
because that option always generates debug messages in the kernel
log; this way you can see the internal state without seeing any
debugging message.
