For S,G entries, thatdeletion calls back into br_multicast_sg_del_exclude_ports(), so a largenumber of STAR_EXCL ports consumes one kernel stack frame per port and canhit the stack guard page.\nKeep the complete port-group deletion path for cleanup, but suppress theS,G exclude-port cleanup while that helper is already walking the sameentry. Normal deletion callers retain the existing
