net/ixgbe: enable IPv6 mask in flow rules

[ upstream commit cba954b7bedaa7d0baea1ddc39fd0199015f583c ]

Add IPv6 addr mask and L4 mask support for rte_flow APIs.

IPv6 flow rules do not take effect in ixgbe when set
IPv6 addr mask and L4 mask to default value as 0xFF.

Set IPv6 addr mask and L4 mask as 0 to enable fields
can fix this issue.
