    ice: enable parsing IPSEC SPI headers for RSS · 86006f99
    Jesse Brandeburg authored
    The COMMS package can enable the hardware parser to recognize IPSEC
    frames with ESP header and SPI identifier.  If this package is available
    and configured for loading in /lib/firmware, then the driver will
    succeed in enabling this protocol type for RSS.
    
    This in turn allows the hardware to hash over the SPI and use it to pick
    a consistent receive queue for the same secure flow. Without this all
    traffic is steered to the same queue for multiple traffic threads from
    the same IP address. For that reason this is marked as a fix, as the
    driver supports the model, but it wasn't enabled.
    
    If the package is not available, adding this type will fail, but the
    failure is ignored on purpose as it has no negative affect.
