(Simon Horman)\n\nChanges in v3:\n- Modify condition from \"if (duplex == DUPLEX_HALF)\" to\n \"if (duplex != DUPLEX_FULL)\". (Simon Horman)\n\nChanges in v2:\n- When forcing half-duplex, set hw->fc.requested_mode = igc_fc_none,\n since half-duplex cannot support flow control per IEEE 802.3.\n (Simon Horman)\n- Split the original single patch into three patches for clarity:\n patches 1 and 2 are preparatory cleanups; patch 3 carries the\n functional change.\n\nv4 at:\nhttps://patchwork.ozlabs.org/project/intel-wired-lan/cover/20260428060009.311393-1-khai.wen.tan@linux.intel.com/\n\nv3 at:\nhttps://patchwork.ozlabs.org/project/intel-wired-lan/cover/20260422155701.7420-1-khai.wen.tan@linux.intel.com/\n\nv2 at:\nhttps://patchwork.kernel.org/project/netdevbpf/patch/20260416015520.6090-4-khai.wen.tan@linux.intel.com/\n\nv1 at:\nhttps://patchwork.ozlabs.org/project/intel-wired-lan/patch/20260409072747.217836-1-khai.wen.tan@linux.intel.com/\n\nFaizal Rahim (4):\n igc: remove unused autoneg_failed field\n igc: move autoneg-enabled settings into igc_handle_autoneg_enabled()\n igc: replace goto out with direct returns in\n igc_config_fc_after_link_up()\n igc: add support for forcing link speed without autonegotiation\n\n drivers/net/ethernet/intel/igc/igc_base.c | 35 +++-\n drivers/net/ethernet/intel/igc/igc_defines.h | 9 +-\n drivers/net/ethernet/intel/igc/igc_ethtool.c | 210 +++++++++++++------\n drivers/net/ethernet/intel/igc/igc_hw.h | 10 +-\n drivers/net/ethernet/intel/igc/igc_mac.c | 35 ++--\n drivers/net/ethernet/intel/igc/igc_main.c | 2 +-\n drivers/net/ethernet/intel/igc/igc_phy.c | 65 +++++-\n drivers/net/ethernet/intel/igc/igc_phy.h | 1 +\n 8 files changed, 268 insertions(+), 99 deletions(-)\n\n--\n2.43.0"}
