mlxsw: spectrum_mr: Convert into using mr_mfc
Current multicast routing logic in driver assumes it's always meant to deal with IPv4 multicast routes, leaving several placeholders for later IPv6 support [currently usually WARN()]. This patch changes the driver's internal multicast route struct into holding a common mr_mfc instead of the IPv4 mfc_cache. The various placeholders are grouped into 2: - Functions that require only the common bits; These remain and the restriction for IPv4-only is lifted. - Function that require IPv4-specifics - for handling these functions we add sets of operations that encapsulate the protocol differences Signed-off-by: Yuval Mintz <yuvalm@mellanox.com> Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
