> Flex-bytes allows for packet matching based on an offset and value. This is
> supported via the ethtool user-def option.  It is specified by providing an
> offset followed by a 2 byte match value. Offset is measured from the start of
> the MAC address.
> 
> The following restrictions apply to flex-bytes. The specified offset must be an
> even number and be smaller than 0x1fe.
> 
> Example usage:
> 
> ethtool -N eth0 flow-type tcp4 src-ip 192.168.0.55 dst-ip 172.16.0.55 \ src-port
> 12 dst-port 13 user-def 0x10ffff action 32
