ice: Support GTP-U and GTP-C offload in switchdev
Add support for creating filters for GTP-U and GTP-C in switchdev mode. Add support for parsing GTP-specific options (QFI and PDU type) and TEID. 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: GTP-U with outer IPv6 offload is not supported yet. Note: GTP-U with no payload offload is not supported yet.
