    wlcore: consolidate tx_seq handling on recovery · 93d5d100
    Arik Nemtsov authored
    Accumulate the total number of sent packets per-link to find out how far
    the encryption sequence number has progressed. Use this number as the
    initial security sequence number after recovery.
    
    This consolidates security sequence handling for both chip families, as
    we no longer have to rely on 12xx specific Tx completion.
    
    A fortunate side effect of this is correct management of seq numbers for
    AP roles and multi-role scenarios.
    
    When a link is removed we save the last seq number on a persistent part
    of the wlvif. This helps the data survive through recoveries/suspends,
    which also entail changes in the hlid of the link.
    
    This functionality is STA only currently.
