What is ethAutoNegSupported?

Reports whether auto-negotiation is actually operating on the link, true only when ethAutoNegAdminStatus is enabled and the remote end also supports auto-negotiation. Admins check this to distinguish "auto-neg is turned on" from "auto-neg is actually working," since the latter also depends on the far-end device.
