Add a debugfs file showing the number of failure of

not with respect to a specific reason. This patch
counts the number of packet drop due to mic failure.

What's the value of this, shouldn't wpa_s/hostapd start countermeasures
pretty quickly?

This will just be a counter which keeps track of the number of mic failures. Debugfs already had Rx dropped packet counter. This would provide more granularity in respect to the reason of packet drop.
Yes, wpa_s/hostapd will start countermeasure quickly.
