net: switch to using PHY_INTERFACE_MODE_10GBASER rather than 10GKR
Switch network drivers, phy drivers, and SFP/phylink over to use the more correct 10GBASE-R, rather than 10GBASE-KR. 10GBASE-KR is backplane ethernet, which is 10GBASE-R with autonegotiation on top, which our current usage on the affected platforms does not have. The only remaining user of PHY_INTERFACE_MODE_10GKR is the Aquantia PHY, which has a separate mode for 10GBASE-KR. For Marvell mvpp2, we detect 10GBASE-KR, and rewrite it to 10GBASE-R for compatibility with existing DT - this is the only network driver at present that makes use of PHY_INTERFACE_MODE_10GKR. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
