net/mlx5: support RSS expansion for IPv6 GRE

Browse Source 
Currently RSS expansion only support IPv4 as GRE payload or
delivery protocol (RFC2784). IPv6 as GRE payload or delivery protocol
(RFC7676) is not supported.

This patch add RSS expansion for RFC7676 so PMD can expand flow item
correctly.
