mac80211: fix association to 20/40 MHz VHT networks
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 Cc: stable@vger.kernel.org Fixes: f2d9d270c15ae ("mac80211: support VHT association") Reported-by: Tim Nelson <tim.l.nelson@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
