Introduce classifying by metadata extracted by the tunnel device.
Outer header fields - source/dest ip and tunnel id, are extracted from
the metadata when classifying.
For example, the following will add a filter on the ingress Qdisc of shared
vxlan device named 'vxlan0'. To forward packets with outer src ip
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: \
flower \
enc_src_ip 11.11.0.2 \
enc_dst_ip 11.11.0.1 \
enc_key_id 11 \
dst_ip 11.11.11.1 \
action mirred egress redirect dev vnet0

Classification according to vlan id and vlan priority.
Example script that adds vlan filter:

tc qdisc add dev ens4f0 ingress
# add a flower filter with vlan id and priority classification

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.
ethtool -K enp0s9 hw-tc-offload on
# add a flower filter with skip-sw flag.
tc filter add dev enp0s9 protocol ip parent ffff: flower \
ip_proto 1 indev enp0s9 skip_sw \
action drop
# add a flower filter with skip-hw flag.
tc filter add dev enp0s9 protocol ip parent ffff: flower \
ip_proto 3 indev enp0s9 skip_hw \
action drop
