Can we always assume that the ANER has the LPAN bit set if the
partner supports NWAY at this point? A switch should start an
autonegotiotion cycle when the link is established, but I didn't
find out whether our ANER gets set if we don't have autonegotiation
enabled (the BMCR_AUTOEN bit) at this time. The standard doesn't
go into details here. (Btw, does "isolated" mean "link down"?)
There is also a bootstrap problem if two machines are connected
I don't see what this condition is necessary for, so I'd remove it.

best regards
