[PATCH net-next 07/15] mlxsw: reg: Configure RIF to forward IPv6 multicast packets

[Ido Schimmel <idosch@mellanox.com>]

From: Yuval Mintz <yuvalm@mellanox.com>

Similarly to what was done in commit 4af5964e5888 ("mlxsw: reg:
Configure RIF to forward IPv4 multicast packets by default") we now set
two additional bits to allow IPv6 multicast forwarding.
