The commands destined for the E-switch are transposed to\nTC-flower rules and are send, as Netlink messages, to the mlx5 driver,\nor more precisely to the netdev which represent the mlxsw port.\nWith the addition to the PMD of E-switch configuration via DR\n(direct verbs rules) it is now possible to configure the E-switch\nusing these commands instead of using TC-Flower messages.\nDoing so will allow us to remove the TCF support and the dependency\nof libmnl from the PMD.\nThe purpose of this RFC is to propose configuring the E-switch\nflow filtering using DR, to remove the TCF support from the PMD and\nto remove the dependency of the PMD in libmnl.\nAs for today VLAN insertion or removal is not supported in DR, this\nsupport will be added in separate commits.\n\nMoti Haimovsky (2):\n net/mlx5: fix testpmd crash on null-flow drv opts\n net/mlx5: remove TCF support from PMD\n\n doc/build-sdk-meson.txt | 2 +-\n doc/guides/nics/mlx5.rst | 19 -\n doc/guides/platform/bluefield.rst | 4 -\n drivers/net/mlx5/Makefile | 303 --\n drivers/net/mlx5/meson.build | 123 +-\n drivers/net/mlx5/mlx5.c | 32 -\n drivers/net/mlx5/mlx5.h | 3 -\n drivers/net/mlx5/mlx5_flow.c | 43 +-\n drivers/net/mlx5/mlx5_flow.h | 25 -\n drivers/net/mlx5/mlx5_flow_tcf.c | 6382 -------------------------------------\n mk/rte.app.mk | 2 +-\n 11 files changed, 24 insertions(+), 6914 deletions(-)\n delete mode 100644 drivers/net/mlx5/mlx5_flow_tcf.c" }
