So a speeds can be achieved with different\nnumber of lanes. For example, the following solutions can be used to\nimplement 100G:\n1. Combines four 25G lanes\n2. Combines two 50G lanes\n3. A single 100G lane\n\nIt is assumed that two ports are interconnected and the two ports support\nthe above three solutions. But, we just configured the speed to 100G and\none port uses four 25G lanes by default and the other port uses two 50G lanes\nby default, the port cannot be up. In this case, we need to configure the\nports to use the same solutions (for example, uses two 50G lanes) so that\nthe ports can be up.\n\nThis patch set add support setting lanes for ethdev. application can use\nthis feature to configure lanes to help select the same solutions.\n\nIn addition, modify the testpmd and hns3 driver to adapt to it.\n\nchange log:\nv1->v2:\n - ethdev updata parse link mode info function name\n - hns3 driver modify report FEC capability\n - testpmd add a command to config speed with lanes\n - update UT and some code rectification\n\nDengdui Huang (6):\n ethdev: support setting lanes\n test: updated UT for setting lanes\n ethdev: add function to parse link mode info\n net/hns3: use parse link mode info function\n net/hns3: support setting lanes\n app/testpmd: support setting lanes\n\n app/test-pmd/cmdline.c | 199 +++++++++-----\n app/test-pmd/config.c | 78 ++++--\n app/test/test_ethdev_link.c | 18 +-\n doc/guides/rel_notes/release_24_03.rst | 11 +\n doc/guides/testpmd_app_ug/testpmd_funcs.rst | 9 +\n drivers/net/bnxt/bnxt_ethdev.c | 3 +-\n drivers/net/hns3/hns3_cmd.h | 15 +-\n drivers/net/hns3/hns3_common.c | 2 +\n drivers/net/hns3/hns3_ethdev.c | 206 ++++++++------\n drivers/net/hns3/hns3_ethdev.h | 2 +\n lib/ethdev/ethdev_linux_ethtool.c | 208 +++++++-------\n lib/ethdev/ethdev_private.h | 4 +\n lib/ethdev/ethdev_trace.h | 4 +-\n lib/ethdev/meson.build | 2 +\n lib/ethdev/rte_ethdev.c | 284 ++++++++++++++++++--\n lib/ethdev/rte_ethdev.h | 104 +++++--\n lib/ethdev/version.map | 7 +\n 17 files changed, 829 insertions(+), 327 deletions(-)" }
