Classification according to vlan id and vlan priority.

 tc qdisc add dev ens4f0 ingress

 # add a flower filter with vlan id and priority classification
 tc filter add dev ens4f0 protocol 802.1Q parent ffff: \
	flower \
		indev ens4f0 \
		vlan_ethtype ipv4 \
		vlan_id 100 \

Amir Vadai cfcabf18d8 tc: flower: Add skip_{hw|sw} support
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
