Masashi Honma 7813b7c34d nl80211: Fix a memory leak on deinit with HT enabled mesh 
Commit a70cd0db87 ('nl80211: Don't
register for Beacon frames for IEEE 802.11ad AP') could cause a trailing
memory leak on IEEE 802.11n enabled mesh. This commit fixes the issue.

This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
