From: Raju Lakkaraju <Raju.Lakkaraju@xxxxxxxxxxxxx> [ 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.
