From: Ido Schimmel <idosch@nvidia.com> Propagate extack to mlxsw_sp_port_attr_br_pre_flags_set() in order to communicate error messages related to bridge port flag validation. Example: # bridge link set dev swp1 locked on Error: mlxsw_spectrum: Unsupported bridge port flag. More error messages will be added in subsequent patches.
