+ *
+ * @IFLA_BRPORT_MODE
+ * Set the bridge port mode. See *BRIDGE_MODE_HAIRPIN* for more details.
+ *
+ * @IFLA_BRPORT_GUARD
+ * Controls whether STP BPDUs will be processed by the bridge port. By
+ * default, the flag is turned off to allow BPDU processing. Turning this
+ * flag on will disable the bridge port if a STP BPDU packet is received.
+ *
+ * If the bridge has Spanning Tree enabled, hostile devices on the network
+ * may send BPDU on a port and cause network failure. Setting *guard on*
+ * will detect and stop this by disabling the port. The port will be
+ * restarted if the link is brought down, or removed and reattached.
+ *
+ * @IFLA_BRPORT_PROTECT
+ * Controls whether a given port is allowed to become a root port or not.
+ * Only used when STP is enabled on the bridge. By default the flag is off.
+ *
+ * This feature is also called root port guard. If BPDU is received from a
+ * leaf (edge) port, it should not be elected as root port. This could
+ * be used if using STP on a bridge and the downstream bridges are not fully
+ * trusted; this prevents a hostile guest from rerouting traffic.
+ *
+ * @IFLA_BRPORT_FAST_LEAVE
+ * This flag allows the bridge to immediately stop multicast traffic
+ * forwarding on a port that receives an IGMP Leave message. It is only used
+ * when IGMP snooping is enabled on the bridge. By default the flag is off.
+ *
+ * @IFLA_BRPORT_LEARNING
+ * Controls whether a given port will learn *source* MAC addresses from
+ * received traffic or not. Also controls whether dynamic FDB entries
+ * (which can also be added by software) will be refreshed by incoming
+ * traffic. By default this flag is on.
+ *
+ * @IFLA_BRPORT_UNICAST_FLOOD
+ * Controls whether unicast traffic for which there is no FDB entry will
+ * be flooded towards this port. By default this flag is on.
+ *
+ * @IFLA_BRPORT_PROXYARP
+ * Enable proxy ARP on this port.
+ *
+ * @IFLA_BRPORT_LEARNING_SYNC
+ * Controls whether a given port will sync MAC addresses learned on device
+ * port to bridge FDB.
+ *

+ *
+ * *mcast_to_unicast* works on top of the multicast snooping feature of the
+ * bridge. Which means unicast copies are only delivered to hosts which
+ * are interested in unicast and signaled this via IGMP/MLD reports previously.
+ *
+ * This feature is intended for interface types which have a more reliable
+ * and/or efficient way to deliver unicast packets than broadcast ones
+ * (e.g. WiFi).
+ *
+ * However, it should only be enabled on interfaces where no IGMPv2/MLDv1
+ * report suppression takes place. IGMP/MLD report suppression issue is
+ * usually overcome by the network daemon (supplicant) enabling AP isolation
+ * and by that separating all STAs.
+ *
+ * Delivery of STA-to-STA IP multicast is made possible again by enabling
+ * and utilizing the bridge hairpin mode, which considers the incoming port
+ * as a potential outgoing port, too (see *BRIDGE_MODE_HAIRPIN* option).
+ * Hairpin mode is performed after multicast snooping, therefore leading
+ * to only deliver reports to STAs running a multicast router.
+ *
+ * @IFLA_BRPORT_VLAN_TUNNEL
+ * Controls whether vlan to tunnel mapping is enabled on the port.
+ * By default this flag is off.
+ *
+ * @IFLA_BRPORT_BCAST_FLOOD
+ * Controls flooding of broadcast traffic on the given port. By default
+ * this flag is on.
+ *
+ * @IFLA_BRPORT_GROUP_FWD_MASK
+ * Set the group forward mask. This is a bitmask that is applied to
+ * decide whether to forward incoming frames destined to link-local
+ * addresses. The addresses of the form are 01:80:C2:00:00:0X (defaults
+ * to 0, which means the bridge does not forward any link-local frames
+ * coming on this port).
+ *
+ * @IFLA_BRPORT_NEIGH_SUPPRESS
+ * Controls whether neighbor discovery (arp and nd) proxy and suppression
+ * is enabled on the port. By default this flag is off.
+ *
+ * @IFLA_BRPORT_ISOLATED
+ * Controls whether a given port will be isolated, which means it will be
+ * able to communicate with non-isolated ports only. By default this
+ * flag is off.
+ *
+ * @IFLA_BRPORT_BACKUP_PORT
+ * Set a backup port. If the port loses carrier all traffic will be
+ * redirected to the configured backup port. Set the value to 0 to disable
+ * it.
+ *
+ * @IFLA_BRPORT_MRP_RING_OPEN
+ *
+ * @IFLA_BRPORT_MRP_IN_OPEN
+ *
+ * @IFLA_BRPORT_MCAST_EHT_HOSTS_LIMIT
+ * The number of per-port EHT hosts limit. The default value is 512.
+ * Setting to 0 is not allowed.
+ *
+ * @IFLA_BRPORT_MCAST_EHT_HOSTS_CNT
+ * The current number of tracked hosts, read only.
+ *
+ * @IFLA_BRPORT_LOCKED
+ * Controls whether a port will be locked, meaning that hosts behind the
+ * port will not be able to communicate through the port unless an FDB
+ * entry with the unit's MAC address is in the FDB. The common use case is
+ * that hosts are allowed access through authentication with the IEEE 802.1X
+ * protocol or based on whitelists. By default this flag is off.
+ *
+ * Please note that secure 802.1X 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 802.1X 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.
