By default this flag is off . * * Please note that secure 802 . 1 X deployments should always use the * * BR_BOOLOPT_NO_LL_LEARN * flag , to not permit the bridge to populate its * FDB based on link - local ( EAPOL ) traffic received on the port . * * @ IFLA_BRPORT_MAB * Controls whether a port will use MAC Authentication Bypass ( MAB ) , a * technique through which select MAC addresses may be allowed on a locked * port , without using 802 . 1 X authentication . Packets with an unknown source * MAC address generates a " locked " FDB entry on the incoming bridge port . * The common use case is for user space to react to these bridge FDB * notifications and optionally replace the locked FDB entry with a normal * one , allowing traffic to pass for whitelisted MAC addresses . * * Setting this flag also requires * IFLA_BRPORT_LOCKED * and * * IFLA_BRPORT_LEARNING * . * IFLA_BRPORT_LOCKED * ensures that unauthorized * data packets are dropped , and * IFLA_BRPORT_LEARNING * allows the dynamic * FDB entries installed by user space ( as replacements for the locked FDB * entries ) to be refreshed and / or aged out . * * @ IFLA_BRPORT_MCAST_N_GROUPS * * @ IFLA_BRPORT_MCAST_MAX_GROUPS * Sets the maximum number of MDB entries that can be registered for a * given port . Attempts to register more MDB entries at the port than this * limit allows will be rejected , whether they are done through netlink * ( e . g . the bridge tool ) , or IGMP or MLD membership reports . Setting a * limit of 0 disables the limit . The default value is 0 . * * @ IFLA_BRPORT_NEIGH_VLAN_SUPPRESS * Controls whether neighbor discovery ( arp and nd ) proxy and suppression is * enabled for a given port . By default this flag is off . * * Note that this option only takes effect when * IFLA_BRPORT_NEIGH_SUPPRESS * * is enabled for a given port . * * @ IFLA_BRPORT_BACKUP_NHID * The FDB nexthop object ID to attach to packets being redirected to a * backup port that has VLAN tunnel mapping enabled ( via the * * IFLA_BRPORT_VLAN_TUNNEL * option ) . Setting a value of 0 ( default ) has * the effect of not attaching any ID . enum {/* Spanning tree state */ /* " priority */ /* " cost */ /* mode (hairpin) */ /* bpdu guard */ /* root port protection */ /* multicast fast leave */ /* mac learning */ /* flood unicast traffic */ /* proxy ARP */ /* mac learning sync from device */ /* proxy ARP for Wi-Fi */ /* designated root */ /* designated bridge */ #define IFLA_BRPORT_MAX (__IFLA_BRPORT_MAX - 1 )struct ifla_cacheinfo {/* ipv6InterfaceTable updated timestamp */ enum {#define IFLA_INFO_MAX (__IFLA_INFO_MAX - 1 )/* VLAN section */ enum {#define IFLA_VLAN_MAX (__IFLA_VLAN_MAX - 1 )struct ifla_vlan_flags {enum {#define IFLA_VLAN_QOS_MAX (__IFLA_VLAN_QOS_MAX - 1 )struct ifla_vlan_qos_mapping {/* MACVLAN section */ enum {#define IFLA_MACVLAN_MAX (__IFLA_MACVLAN_MAX - 1 )enum macvlan_mode {1 , /* don't talk to other macvlans */ 2 , /* talk to other ports through ext bridge */ 4 , /* talk to bridge ports directly */ 8 ,/* take over the underlying device */ 16 ,/* use source MAC address list to assign */ enum macvlan_macaddr_mode {#define MACVLAN_FLAG_NOPROMISC 1 #define MACVLAN_FLAG_NODST 2 /* skip dst macvlan if matching src macvlan */ /* VRF section */ enum {#define IFLA_VRF_MAX (__IFLA_VRF_MAX - 1 )enum {#define IFLA_VRF_PORT_MAX (__IFLA_VRF_PORT_MAX - 1 )/* MACSEC section */ enum {#define IFLA_MACSEC_MAX (__IFLA_MACSEC_MAX - 1 )/* XFRM section */ enum {#define IFLA_XFRM_MAX (__IFLA_XFRM_MAX - 1 )enum macsec_validation_type {0 ,1 ,2 ,1 ,enum macsec_offload {0 ,1 ,2 ,1 ,/* IPVLAN section */ enum {#define IFLA_IPVLAN_MAX (__IFLA_IPVLAN_MAX - 1 )enum ipvlan_mode {0 ,#define IPVLAN_F_PRIVATE 0 x01#define IPVLAN_F_VEPA 0 x02/* Tunnel RTM header */ struct tunnel_msg {/* netkit section */ enum netkit_action {1 ,0 ,2 ,7 ,enum netkit_mode {/* NETKIT_SCRUB_NONE leaves clearing skb->{mark,priority} up to * the BPF program if attached .
