Following series adds support to enable creation of multiple representors under one base device. There may be scenarios where port representors for multiple PFs or VFs under PF are required and all these representor ports created under a single pci device. Marvell CNXK port representor solution is designed around this scenario where all representors are backed by a single switch device.
Earlier this change was implemented as part of the Marvell CNXK port representor series but after suggestions from Thomas we would like to propose these changes in common code. https://patches.dpdk.org/project/dpdk/patch/20231219174003.72901-25-hka...@marvell.com/#166785 V2: - Updated the multiple representor devarg pattern to list i.e. representor=[pf[0-1],pf2vf[1,2-3],[4-5]] - Introduced size of array as third argument to rte_eth_devargs_parse() to avoid array corruption - Squashed separate document patch Harman Kalra (1): ethdev: parsing multiple representor devargs string doc/guides/prog_guide/poll_mode_drv.rst | 4 +- .../prog_guide/switch_representation.rst | 1 + drivers/net/bnxt/bnxt_ethdev.c | 4 +- drivers/net/enic/enic_ethdev.c | 4 +- drivers/net/i40e/i40e_ethdev.c | 4 +- drivers/net/ice/ice_dcf_ethdev.c | 4 +- drivers/net/ixgbe/ixgbe_ethdev.c | 4 +- drivers/net/mlx5/linux/mlx5_os.c | 8 +- .../net/nfp/flower/nfp_flower_representor.c | 4 +- drivers/net/sfc/sfc_ethdev.c | 4 +- lib/ethdev/ethdev_driver.c | 105 +++++++++++++++--- lib/ethdev/ethdev_driver.h | 9 +- 12 files changed, 119 insertions(+), 36 deletions(-) -- 2.18.0
