3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
commit cb664981607a6b5b3d670ad57bbda893b2528d96 upstream.
When a VHT network uses 20 or 40 MHz as per the HT operation information, the channel center frequency segment 0 field in the VHT operation information is reserved, so ignore it.
This fixes association with such networks when the AP puts 0 into the field, previously we'd disconnect due to an invalid channel with the message wlan0: AP VHT information is invalid, disable VHT
