Done for v3. Switched the NHA_FDB_PORT policy to NLA_POLICY_MIN(NLA_BE16, 1), so the core rejects a zero destination port for us; the "fdb + gateway" requirement stays in rtm_to_nh_config(). > Why not nhi->fdb_port ? Good catch. Fixed for v3: nh_nlmsg_size_single() now reserves the NHA_FDB_PORT space under "if (nhi->fdb_port)", matching the emit condition in nh_fill_node() so the size calculation and the dump agree and space is only reserved when a port is actually set. Thanks, Jack
