This action could be used before redirecting packets to a shared tunnel
device, or when redirecting packets arriving from a such a device.
The 'unset' action is optional. It is used to explicitly unset the
metadata created by the tunnel device during decap. If not used, the
metadata will be released automatically by the kernel.
The 'set' operation, will set the metadata with the specified values for
the encap.
For example, the following flower filter will forward all ICMP packets
destined to 11.11.11.2 through the shared vxlan device 'vxlan0'. Before
redirecting, a metadata for the vxlan tunnel is created using the
tunnel_key action and it's arguments:
$ tc filter add dev net0 protocol ip parent ffff: \
flower \
ip_proto 1 \
dst_ip 11.11.11.2 \
action tunnel_key set \
src_ip 11.11.0.1 \

id 11 \
action mirred egress redirect dev vxlan0

11.11.0.2, dst ip 11.11.0.1 and tunnel id 11. The packets will be
forwarded to tap device 'vnet0':
$ tc filter add dev vxlan0 protocol ip parent ffff: \

Introduce a new API that exposes a list of vlans per VF (IFLA_VF_VLAN_LIST),
giving the ability for user-space application to specify it for the VF as
an option to support 802.1ad (VST QinQ).
We introduce struct vf_vlan_info, which extends struct vf_vlan and adds
an optional VF VLAN proto parameter.
Default VLAN-protocol is 802.1Q.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older kernel versions.
Suitable ip link tool command examples:
- Set vf vlan protocol 802.1ad (S-TAG)
ip link set eth0 vf 1 vlan 100 proto 802.1ad
- Set vf vlan S-TAG and vlan C-TAG (VST QinQ)
ip link set eth0 vf 1 vlan 100 proto 802.1ad vlan 30 proto 802.1Q
- Set vf to VST (802.1Q) mode
ip link set eth0 vf 1 vlan 100 proto 802.1Q
- Or by omitting the new parameter (backward compatible)

Looks like the real issue is missing definition of priority. What about
this:
use get_be64() in place of get_u64() when parsing input 'sci' parameter,
so that 'sci' can be entered using network byte order regardless the
endianness of target system; use ntohll() when printing out 'sci'. While
at it, improve documentation of 'sci' in ip-link.8.

In this patch we introduce the ability to get UDP specific bearer
options such as remoteip, remoteport, localip and localport.
After some discussions on tipc-discussion on how to handle media
specific options we agreed to pass them after the media.
For media generic bearer options we already do:
$ tipc bearer get OPTION media MEDIA name|device NAME|DEVICE
For the UDP media specific bearer options we introduce in this path:
$ tipc bearer get media udp name NAME OPTION
such as
$ tipc bearer get media udp name NAME remoteip
This allows bash-completion to tab complete only appropriate options,
it makes more logical sense and it scales better. Even though it might
look a little different to the user.
In order to use the existing option parsing framework to do this we
add a flag (OPT_KEY) to the option parsing function.
If the UDP bearer has multiple remoteip addresses associated with it
(replicast) we handle the TIPC_NLA_UDP_MULTI_REMOTEIP flag and send
a TIPC_NL_UDP_GET_REMOTEIP query transparently to the user.

This patch adds support for the stats argument to the bridge
vlan command which will display the per-vlan statistics and the device
each vlan belongs to with its flags. The supported command filtering
options are dev and vid. Also the man page is updated to explain the new
option.
The patch uses the new RTM_GETSTATS interface with a filter_mask to dump
all bridges and ports vlans. Later we can add support for using the
per-device dump and filter it in the kernel instead.
Example:
$ bridge -s vlan show
port vlan id
br0 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
eth1 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
100
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
102
RX: 16897 bytes 93 packets
TX: 0 bytes 0 packets
The format is the same as bridge vlan show but with stats, even though
under the hood the calls done to the kernel are different.

On devices that support TC flower offloads, these flags enable a filter to be
added only to HW or only to SW. skip_sw and skip_hw are mutually exclusive
flags. By default without any flags, the filter is added to both HW and SW,
but no error checks are done in case of failure to add to HW.
With skip-sw, failure to add to HW is treated as an error.
Here is a sample script that adds 2 filters, one with skip_sw and the other
with skip_hw flag.
# add ingress qdisc
tc qdisc add dev enp0s9 ingress
# enable hw tc offload.
