The task of driving the PHY chip is implemented in some firmware versions. If firmware supports the phy driver, it will report a capability flag to driver in probing process. The driver determines whether to support PF device with copper phys based on the capability bit. If supported, the driver set a flag indicating that the firmware takes over the PHY, and then the firmware initializes the PHY. This patch supports the query of link status and link info, and existing basic features for PF device with copper phys.
