From: Zheng Zengkai <zhengzengkai@huawei.com> From: Raju Lakkaraju <Raju.Lakkaraju@microchip.com> stable inclusion from stable-v6.6.3 commit 0570c9fd1609da5d981a181892fa74bbd1ca860a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit e27aca3760c08b7b05aea71068bd609aa93e7b35 ] Add a quirk for a copper SFP that identifies itself as "FS" "SFP-2.5G-T". This module's PHY is inaccessible, and can only run at 2500base-X with the host without negotiation. Add a quirk to enable the 2500base-X interface mode with 2500base-T support and disable auto negotiation.
