    mac80211: add a single-transaction driver op to switch contexts · 1a5f0c13
    Luciano Coelho authored
    In some cases, when the driver is already using all the channel
    contexts it can handle at once, we have to do an in-place switch
    (ie. we cannot afford using an extra context temporarily for the
    transaction).  But some drivers may not support switching the channel
    context assigned to a vif on the fly (ie. without unassigning and
    assigning it) while others may only work if the context is changed on
    the fly, without unassigning it first.
    
    To allow these different scenarios, add a new driver operation that
    let's the driver decide how to handle an in-place switch.
