When dealing with some copper modules, we can't positively know the module capabilities are until we have probed the PHY. Without the full capabilities, we may end up failing a module that we could otherwise drive with a restricted set of capabilities. An example of this would be a module with a NBASE-T PHY plugged into a host that supports phy interface modes 2500BASE-X and SGMII. The PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes, which means a subset of the capabilities are compatible with the host. However, reading the module EEPROM leads us to believe that the module only supports ethtool link mode 10GBASE-T, which is incompatible with the host - and thus results in the module being rejected. This patch adds an extra notification which are triggered after the SFP module's PHY probe, and a corresponding notification just before the PHY is removed.
