ice: Enable flex-bytes support
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
