    mwifiex: fix 802.11n/WPA detection · df612421
    Brian Norris authored
    Commit 63d7ef36 ("mwifiex: Don't abort on small, spec-compliant
    vendor IEs") adjusted the ieee_types_vendor_header struct, which
    inadvertently messed up the offsets used in
    mwifiex_is_wpa_oui_present(). Add that offset back in, mirroring
    mwifiex_is_rsn_oui_present().
    
    As it stands, commit 63d7ef36 breaks compatibility with WPA (not
    WPA2) 802.11n networks, since we hit the "info: Disable 11n if AES is
    not supported by AP" case in mwifiex_is_network_compatible().
    
    Fixes: 63d7ef36 ("mwifiex: Don't abort on small, spec-compliant vendor IEs")
