There are still corner cases of 10/100 autoneg issues, I concur with
others and  locally run autoneg  by default and hard-code exceptions
(less than a dozen in 20K ports).

For those thinking hard coding more than necessary, note that
autonegotiation is *mandatory* on 1000TX ethernet (at least to comply
with IEEE specs).
