Subject: [PATCH net-next 3/5] net: phy: realtek: reunify C22 and C45 drivers
Reunify the split C22/C45 drivers for the RTL8221B-VB-CG 2.5Gbps and
RTL8221B-VM-CG 2.5Gbps PHYs back into a single driver.
This is possible now by using all the driver operations previously used
by the C45 driver, as transparent access to all MMDs including
MDIO_MMD_VEND2 is now possible also over Clause-22 MDIO.
