net: phy: pass supported PHY interface types to phylib
Pass the supported PHY interface types to phylib so that PHY drivers can select an appropriate host configuration mode for their interface according to the host capabilities. This is only done for SFP modules presently. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
