    octeontx2-af: Add support for stripping STAG/CTAG · 86cea61d
    Tomasz Duszynski authored
    This works by shadowing existing UCAST MCAM entry
    with a new one additionally matching either NPC_LT_LB_CTAG
    or NPC_LT_LB_STAG. For this to fully work one needs to
    send properly configured NIX_VTAG_CFG message afterwards i.e with
    strip and capture enabled and type set to 0.
    
    On receiving tagged packet NIX will remove outer VLAN and capture
    TCI in NIX_RX_PARSE_S.
    
    Also simplified RX Vtag configuration flow
    With this setting STRIP/CAPTURE VTAG actions separately would be
    possible. Following combinations are possible: STRIP,
    STRIP and CAPTURE, CAPTURE or nothing (0 disables respective actions).
