commit 445bed5c4d859575951361e432024396b938f863 Author: Stephan de Wit <[email protected]> AuthorDate: 2024-02-02 19:17:14 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2024-02-02 19:21:00 +0000 axgbe: Various link stability and module compatibilty improvements Move the phy_stop() routine to if_detach() to prevent link interruptions when configuring the interface. Accompanying this is a sanity check using phy_started, which was already there but remained unused. We do not move phy_start(), as the logic there is needed for any init routine, be it attach or start. Also bring in the linux PMA_PLL change which addresses the flapping of back-to-back fiber connections. Use miibus for SFP PHYs up to 1G copper. We retry in cases where the PHY is not directly reachable. Set the correct IFM_100_SGMII flag when the phy speed has been set to 100. We remove xgbe_phy_start_aneg() since it's handled by miibus. Add support for 100 and 1000 BASE-BX fiber modules Add support for 25G multirate DACs which are capable of 10G. While here, also fixup the LINK_ERR state. It was impossible to recover from this previously. [[ Note: light style fixes by imp, slight commit message adjustment, and a warning that I don't have the hardware to validate, but the changes do track the commit message and seem otherwise OK ]] Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/768 --- sys/dev/axgbe/if_axgbe_pci.c | 4 +- sys/dev/axgbe/xgbe-common.h | 8 ++ sys/dev/axgbe/xgbe-i2c.c | 5 +- sys/dev/axgbe/xgbe-mdio.c | 12 +- sys/dev/axgbe/xgbe-phy-v2.c | 271 ++++++++++++++++++++++++++++++------------- 5 files changed, 209 insertions(+), 91 deletions(-) diff --git a/sys/dev/axgbe/if_axgbe_pci.c b/sys/dev/axgbe/if_axgbe_pci.c index dcf769d14f75..beb4ff338dc7 100644 --- a/sys/dev/axgbe/if_axgbe_pci.c +++ b/sys/dev/axgbe/if_axgbe_pci.c @@ -1534,6 +1534,7 @@ axgbe_if_detach(if_ctx_t ctx) mac_res[0] = pdata->xgmac_res;
