To create a filter for GTP, create a GTP-type netdev with ip tool, enable hardware offload, add qdisc and add a filter in tc: ip link add $GTP0 type gtp role hsize ethtool -K $PF0 hw-tc-offload on tc qdisc add dev $GTP0 ingress tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \ action mirred egress redirect dev $VF1_PR By default, a filter for GTP-U will be added. To add a filter for GTP-C, specify enc_dst_port = 2123, e.g.: tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \ enc_dst_port 2123 action mirred egress redirect dev $VF1_PR Note: outer IPv6 offload is not supported yet. Note: GTP-U with no payload offload is not supported yet. ICE COMMS package is required to create a filter as it contains GTP profiles. Changes in iproute2 [1] are required to be able to add GTP netdev and use GTP-specific options (QFI and PDU type).
