    Errata 35038
      Software sets NIX_AF_RX_SW_SYNC[ENA] to sync (flush) in-flight packets
      the RX data path before configuration changes (e.g. disabling one or
      more RQs). Hardware clears [ENA] to indicate sync is done
    
      An issue exists whereby NIX may clear NIX_AF_RX_SW_SYNC [ENA] too
      early.
    
    Errata 35057
      NIX may corrupt internal state when conditional clocks turn off.
      So turnon all clocks by default.
    
    Errata 35786
     Parse nibble enable NPC configuration for KEY generation has to be
     identical for both Rx and Tx interfaces.
    
    Also corrected endianness configuration for NIX i.e NIX_AF_CFG[AF_BE]
    is bit8 and not bit1.
