[dpdk-dev] [PATCH v2 1/2] compressdev: replace mbuf scatter gather flag

The current mbuf scatter gather feature flag is too ambiguous, as it is not clear if input and/or output buffers can be scatter gather mbufs or not. Therefore, three new flags will replace this flag: - RTE_COMP_FF_OUT_OF_PLACE_SGL_IN_SGL_OUT - RTE_COMP_FF_OUT_OF_PLACE_SGL_IN_FB_OUT - RTE_COMP_FF_O

[dpdk-dev] [PATCH 6/6] net/mlx5: add port ID pattern item to switch flow rules

This enables flow rules to match traffic coming from a different DPDK port ID associated with the device (PORT_ID pattern item), mainly for the convenience of applications that want to deal with a single port ID for all flow rules associated with some physical device. Testpmd example: - Creating

[dpdk-dev] [PATCH 5/6] net/mlx5: add VLAN item and actions to switch flow rules

This enables flow rules to explicitly match VLAN traffic (VLAN pattern item) and perform various operations on VLAN headers at the switch level (OF_POP_VLAN, OF_PUSH_VLAN, OF_SET_VLAN_VID and OF_SET_VLAN_PCP actions). Testpmd examples: - Directing all VLAN traffic received on port ID 1 to port ID

[dpdk-dev] [PATCH 4/6] net/mlx5: add L2-L4 pattern items to switch flow rules

This enables flow rules to explicitly match supported combinations of Ethernet, IPv4, IPv6, TCP and UDP headers at the switch level. Testpmd example: - Dropping TCPv4 traffic with a specific destination on port ID 2: flow create 2 ingress transfer pattern eth / ipv4 / tcp dst is 42 / end

[dpdk-dev] [PATCH 3/6] net/mlx5: add fate actions to switch flow rules

This patch enables creation of rte_flow rules that direct matching traffic to a different port (e.g. another VF representor) or drop it directly at the switch level (PORT_ID and DROP actions). Testpmd examples: - Directing all traffic to port ID 0: flow create 1 ingress transfer pattern end ac

[dpdk-dev] [PATCH 2/6] net/mlx5: add framework for switch flow rules

Because mlx5 switch flow rules are configured through Netlink (TC interface) and have little in common with Verbs, this patch adds a separate parser function to handle them. - mlx5_nl_flow_transpose() converts a rte_flow rule to its TC equivalent and stores the result in a buffer. - mlx5_nl_flo

[dpdk-dev] [PATCH 1/6] net/mlx5: lay groundwork for switch offloads

With mlx5, unlike normal flow rules implemented through Verbs for traffic emitted and received by the application, those targeting different logical ports of the device (VF representors for instance) are offloaded at the switch level and must be configured through Netlink (TC interface). This patc

[dpdk-dev] [PATCH 0/6] net/mlx5: add support for switch flow rules

This series adds support for switch flow rules, that is, rte_flow rules applied to mlx5 devices at the switch level. It allows applications to offload traffic redirection between DPDK ports in hardware, while optionally modifying it (e.g. performing encap/decap). For this to work, involved DPDK p
