Implement support for IPV6_USER_FLOW type rules.

Example:
$ ethtool -U ens9 flow-type ip6 src-ip fe80::2 dst-ip fe80::4 action 3
Added rule with ID 0

The example rule will forward packets with the specified source and
destination IP addresses to RX ring 3.

so this checks mask then copies but parse_ip4 copies unconditionally?
why?

Added a similar check in the previous patch.
