> 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.
> 
> If the package is not available, adding this type will fail, but the failure is
> ignored on purpose as it has no negative affect.
