They must also be combined with a\nport redirection action to make sense.\n\nA typical use case is port representors in switchdev mode, with VXLAN\ntraffic encapsulation performed on traffic coming *from* a representor and\ndecapsulation on traffic going *to* that representor, in order to\ntransparently assign a given VXLAN to VF traffic.\n\nSince only ingress is supported, encapsulation flow rules are normally\napplied on a physical port and emit traffic to a port representor. The\nopposite order is used for decapsulation.\n\nLike other mlx5 switch flow rule actions, these are implemented through\nLinux's TC flower API. Since the Linux interface for VXLAN encap/decap\ninvolves virtual network devices (i.e. ip link add type vxlan [...]), the\nPMD automatically spawns them on a needed basis through Netlink calls. The\nadded complexity necessarily results in a rather convoluted PMD\nimplementation.\n\nThis series relies on \"ethdev: add flow API object converter\" [1] which\nshould applied first since testpmd does not provide a means to test VXLAN\nencap otherwise.\n\n[1] https://patches.dpdk.org/project/dpdk/list/?series=1123\n\nAdrien Mazarguil (8):\n net/mlx5: speed up interface index retrieval for flow rules\n net/mlx5: clean up redundant interface name getters\n net/mlx5: rename internal function\n net/mlx5: enhance TC flow rule send/ack function\n net/mlx5: prepare switch flow rule parser for encap offloads\n net/mlx5: add convenience macros to switch flow rule engine\n net/mlx5: add VXLAN encap support to switch flow rules\n net/mlx5: add VXLAN decap support to switch flow rules\n\n drivers/net/mlx5/Makefile | 75 ++\n drivers/net/mlx5/mlx5.c | 74 +-\n drivers/net/mlx5/mlx5.h | 28 +-\n drivers/net/mlx5/mlx5_ethdev.c | 188 ++--\n drivers/net/mlx5/mlx5_flow.c | 16 +-\n drivers/net/mlx5/mlx5_nl.c | 9 +-\n drivers/net/mlx5/mlx5_nl_flow.c | 1763 ++++++++++++++++++++++++++++++++--\n 7 files changed, 1871 insertions(+), 282 deletions(-)" }
