Signed-off-by: Michael Grzeschik Signed-off-by: Oleksij Rempel Reviewed-by: Andrew Lunn --- v1 -> v4: - extracted this change from bigger previous patch v4 -> v5: - added clear of reset bit for ksz8863 reset code - using extra device flag IS_KSZ88x3 instead of is_ksz8795 function - using DSA_TAG_PROTO_KSZ9893 protocol for ksz88x3 instead v5 -> v6: - changed variable order to revers christmas tree - added back missed dropped handling in init_cnt for ksz8863 - disable VLAN support for ksz8863.
