425 on the RX direction - by default the packet will be untagged before being
426 received by VLAN device. Reordering allows to accelerate tagging on egress and
427 to hide VLAN header on ingress so the packet looks like regular Ethernet packet,
428 at the same time it might be confusing for packet capture as the VLAN header
429 does not exist within the packet.

1253 - Do not allow communication between
1255 instances on the same physical interface, even if the external switch supports
1259 - Virtual Ethernet Port Aggregator mode. Data from one
1261 instance to the other on the same physical interface is transmitted over the
1262 physical interface. Either the attached switch needs to support hairpin mode,
1263 or there must be a TCP/IP router forwarding the packets in order to allow
1264 communication. This is the default mode.
1267 - In bridge mode, all endpoints are directly connected to each other,
1268 communication is not redirected through the physical interface's peer.
1270 .BR mode " " passthru " [ " nopromisc " ] "
1271 - This mode gives more power to a single endpoint, usually in
1272 .BR macvtap " mode. It is not allowed for more than one endpoint on the same "
1273 physical interface. All traffic will be forwarded to this endpoint, allowing
1274 virtio guests to change MAC address or set promiscuous mode in order to bridge
1275 the interface or create vlan interfaces on top of it. By default, this mode
1276 forces the underlying interface into promiscuous mode. Passing the
1277 .BR nopromisc " flag prevents this, so the promisc flag may be controlled "
1278 using standard tools.
1281 - allows one to set a list of allowed mac address, which is used to match
1282 against source mac address from received frames on underlying interface. This
1283 allows creating mac based VLAN associations, instead of standard port or tag
1284 based. The feature is useful to deploy 802.1x mac based behavior,
1285 where drivers of underlying interfaces doesn't allows that.

1961 attached to the given device, an error will be thrown. If no XDP/BPF
1962 program is currently attached, the device supports XDP and the program
1963 from the BPF ELF file passes the kernel verifier, then it will be attached
1964 to the device. If the option

1969 no error will be thrown in this case. If no

2195 - add MACADDR to allowed list
2198 - replace allowed list
2201 - remove MACADDR from allowed list
2204 - flush whole allowed list
2209 .SS ip link show - display device attributes
2212 .BI dev " NAME " (default)
2214 specifies the network device to show.
2215 If this argument is omitted all devices in the default group are listed.
2220 specifies what group of devices to show.
2224 only display running interfaces.
2227 .BI master " DEVICE "
2229 specifies the master device which enslaves devices to show.
2234 speficies the VRF which enslaves devices to show.
2239 specifies the type of devices to show.
2241 Note that the type name is not checked against the list of supported types -
2242 instead it is sent as-is to the kernel. Later it is used to filter the returned
2243 interface list by comparing it with the relevant attribute in case the kernel
2244 didn't filter already. Therefore any string is accepted, but may lead to empty
2247 .SS ip link xstats - display extended statistics
2252 specifies the type of devices to display extended statistics for.
2254 .SS ip link afstats - display address-family specific statistics
2259 specifies the device to display address-family statistics for.
2261 .SS ip link help - display help
2265 specifies which help of link type to dislpay.
2269 may be a number or a string from the file
2270 .B @SYSCONFDIR@/group
2271 which can be manually filled.
2277 Shows the state of all network interfaces on the system.
2280 ip link show type bridge
2282 Shows the bridge devices.
2285 ip link show type vlan
2287 Shows the vlan devices.
2290 ip link show master br0
2292 Shows devices enslaved by br0
2295 ip link set dev ppp0 mtu 1400
2297 Change the MTU the ppp0 device.
2300 ip link add link eth0 name eth0.10 type vlan id 10
2302 Creates a new vlan device eth0.10 on device eth0.
2305 ip link delete dev eth0.10
2307 Removes vlan device.
2312 Display help for the gre link type.
2315 ip link add name tun1 type ipip remote 192.168.1.1
2316 local 192.168.1.2 ttl 225 encap gue encap-sport auto
2317 encap-dport 5555 encap-csum encap-remcsum
2319 Creates an IPIP that is encapsulated with Generic UDP Encapsulation,
2320 and the outer UDP checksum and remote checksum offload are enabled.
2323 ip link set dev eth0 xdp obj prog.o
2325 Attaches a XDP/BPF program to device eth0, where the program is
2326 located in prog.o, section "prog" (default section). In case a
2327 XDP/BPF program is already attached, throw an error.
2330 ip -force link set dev eth0 xdp obj prog.o sec foo
2332 Attaches a XDP/BPF program to device eth0, where the program is
2333 located in prog.o, section "foo". In case a XDP/BPF program is
2334 already attached, it will be overridden by the new one.
2337 ip -force link set dev eth0 xdp pinned /sys/fs/bpf/foo
2339 Attaches a XDP/BPF program to device eth0, where the program was
2340 previously pinned as an object node into BPF file system under
2344 ip link set dev eth0 xdp off
2346 If a XDP/BPF program is attached on device eth0, detach it and
2347 effectively turn off XDP for device eth0.
2350 ip link add link wpan0 lowpan0 type lowpan
2352 Creates a 6LoWPAN interface named lowpan0 on the underlying
2353 IEEE 802.15.4 device wpan0.
2356 ip link add dev ip6erspan11 type ip6erspan seq key 102
2357 local fc00:100::2 remote fc00:100::1
2358 erspan_ver 2 erspan_dir ingress erspan_hwid 17
2360 Creates a IP6ERSPAN version 2 interface named ip6erspan00.
