In eSwitch switchdev mode, the device allows hardware offload of the L2/L3/L4, VXLAN, GRETAP, GENEVE, GTP, L2TPv3, and PPPoE TC-Flower exact match rules through the PRs. TC-Flower can be used to offload the kernel data path. Table: Supported Patterns and Input Sets for TC-Flower Hardware Offload shows the pattern types and input sets available for TC-Flower hardware offload programming.

The following actions are supported for HW offload:

Drop (FLOW_ACTION_DROP)

Redirect to an if index (FLOW_ACTION_REDIRECT)

Note:The VLAN ID that is set from the PR netdev is always the outer VLAN for the VLAN. This can be of type 0x8100 (802.1q) or 0x88A8 (802.1ad).

If match/action is requested that cannot be offloaded because it is either unsupported or there are no resources, software must fail the offload and then flush all existing fast-path rules.

The following actions are unsupported in the 800 Series:

VLAN push (id, prio)

VLAN pop

VXLAN encap/decap
