description:
Add IPv6 mask for flow director.

  - FreeBSD: c4f73d5d6a6c0117e08a03920cce69202865ba13 or ix-3.3.18
    DPDK:    21feefa2fcd5899ee26a10be405c17c0a1109860

    Write FDIRIP6M register to allow flow director filter
    to set ipv6 rules without setting ipv6 source/destination address.

  - No functional change because NetBSD doesn't support flow director.
