This update adds support for the VXLAN last 8-bits matching when creating steering rules. At the PCIe probe stage, we create a dummy VXLAN matcher using misc5 to check rdma-core library's capability.
The logic is, group 0 depends on HCA_CAP to enable misc or misc5 for VXLAN matching while group non zero depends on the rdma-core capability. Add a new testpmd pattern field 'last_rsvd' that supports the last 8-bits matching of VXLAN header. The examples for the "last_rsvd" pattern field are as below: 1. ...pattern eth / ipv4 / udp / vxlan last_rsvd is 0x80 / end ... This flow will exactly match the last 8-bits to be 0x80. 2. ...pattern eth / ipv4 / udp / vxlan last_rsvd spec 0x80 vxlan mask 0x80 / end ... This flow will only match the MSB of the last 8-bits to be 1. rongwei liu (2): drivers: add VXLAN header the last 8-bits matching support app/testpmd: support VXLAN last 8-bits field matching app/test-pmd/cmdline_flow.c | 9 ++ app/test-pmd/util.c | 5 +- doc/guides/nics/mlx5.rst | 11 +- doc/guides/testpmd_app_ug/testpmd_funcs.rst | 1 + drivers/common/mlx5/mlx5_devx_cmds.c | 3 + drivers/common/mlx5/mlx5_devx_cmds.h | 6 + drivers/common/mlx5/mlx5_prm.h | 41 +++++- drivers/net/mlx5/linux/mlx5_os.c | 77 ++++++++++ drivers/net/mlx5/mlx5.h | 2 + drivers/net/mlx5/mlx5_flow.c | 26 +++- drivers/net/mlx5/mlx5_flow.h | 4 +- drivers/net/mlx5/mlx5_flow_dv.c | 152 ++++++++++++++------ drivers/net/mlx5/mlx5_flow_verbs.c | 3 +- drivers/vdpa/mlx5/mlx5_vdpa_steer.c | 6 +- 14 files changed, 283 insertions(+), 63 deletions(-) -- 2.27.0
