Autoneg is only a nightmare if you use turn-of-the-millenium era kit,
back when 100Mb/s was a big deal. xl(4) was particularly bad.
On the other hand, for anything Gb capable nowadays connected to a
switch autoneg pretty much just works -- em(4), bce(4) are excellent,
and even re(4) gets this stuff right.
Oh, and as someone else mentioned, 'full duplex' on one of those bastard
devices that claim 10/100 speed because they have *one* 100Mb/s capable
port, and everything else is a 10Mb/s hub... that way madness lies...
Why anyone would use such a thing nowadays I don't know, as even cheapo
DSL routers tend to incorporate Gb switched ports nowadays.
Cheers,
Matthew
