    Subject[PATCH 3.13 026/149] mac80211: fix association to 20/40 MHz VHT networks
    Date
    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

    Fixes: f2d9d270c15ae ("mac80211: support VHT association")
