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: 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 are required to be able to add GTP netdev and use GTP-specific options (QFI and PDU type). This patchset will be submitted separately. --- v2: Adding more CC v3: Fixed mail thread, sorry for spam v4: Added GTP echo response in gtp driver Marcin Szycik (1): ice: Support GTP-U and GTP-C offload in switchdev Michal Swiatkowski (1): ice: Fix FV offset searching Wojciech Drewek (4): gtp: Allow to create GTP device without FDs gtp: Add support for checking GTP device type net/sched: Allow flower to match on GTP options gtp: Implement GTP echo response drivers/net/ethernet/intel/ice/ice.h | 1 + .../net/ethernet/intel/ice/ice_flex_pipe.c | 46 +- .../net/ethernet/intel/ice/ice_flex_pipe.h | 2 +- .../net/ethernet/intel/ice/ice_flex_type.h | 6 +- .../ethernet/intel/ice/ice_protocol_type.h | 19 + drivers/net/ethernet/intel/ice/ice_switch.c | 630 ++++++++++++++++-- drivers/net/ethernet/intel/ice/ice_switch.h | 9 + drivers/net/ethernet/intel/ice/ice_tc_lib.c | 105 ++- drivers/net/ethernet/intel/ice/ice_tc_lib.h | 3 + drivers/net/gtp.c | 286 +++++++- include/net/gtp.h | 42 ++ include/uapi/linux/if_link.h | 1 + include/uapi/linux/if_tunnel.h | 4 +- include/uapi/linux/pkt_cls.h | 15 + net/sched/cls_flower.c | 116 ++++ 15 files changed, 1195 insertions(+), 90 deletions(-)
