    mac80211: upgrade BW of TDLS peers when possible · 0fabfaaf

    Define a station chandef, to be used for wider-bw TDLS peers. When both
    peers support the feature, upgrade the channel bandwidth to the maximum
    allowed by both peers and regulatory. Currently widths up to 80MHz are
    supported in the 5GHz band.
    
    When a TDLS peer connects/disconnects recalculate the channel type of the
    current chanctx.
    Make the chanctx width calculation consider wider-bw TDLS peers and
    similarly fix the max_required_bw calculation for the chanctx min_def.
    Since the sta->bandwidth is calculated only later on, take
    bss_conf.chandef.width as the minimal width for station interface.
    
    Set the upgraded channel width in the VHT-operation set during TDLS setup.
