Trent Piepho 51e2a3846e PHY: Avoid unnecessary aneg restarts ... The PHY's aneg is configured and restarted whenever the link is brought up, e.g. when DHCP is started after the kernel has booted. This can take the link down for several seconds while auto-negotiation is redone. If the advertised features haven't changed, then it shouldn't be necessary to bring down the link and start auto-negotiation over again. genphy_config_advert() is enhanced to return 0 when the advertised features haven't been changed and >0 when they have been. genphy_config_aneg() then uses this information to not call genphy_restart_aneg() if there has been no change.
