Autonegotiation and multi-speed are two entirely different things.
Selecting a single speed doesn't mean turning autoneg off. If you
enable only 1000BASE-T or only 10GBASE-T, the PHY must still go through
autoneg to determine whether it is the clock master for the link.
Enabling multiple speeds doesn't mean turning autoneg on. An SFP+ slot
can take 1G and 10G modules but the modules generally won't support
autoneg.
