    sfc: Add RX packet timestamping for EF10 · bd9a265d
    Jon Cooper authored
    The EF10 firmware can optionally insert RX timestamps in the packet
    prefix.  These only include the clock minor value.  We must also
    enable periodic time sync events on each event queue which provide
    the high bits of the clock value.
    
    [bwh: Combined and rebased several changes.
     Added the above description and some sanity checks for inline vs
     separate timestamps.
     Changed efx_rx_skb_attach_timestamp() to read the packet prefix
     from the skb head area.]
