that is like the worst advice possible.

this comes from a distant past, where some vendors (hello cisco) had
royally screwed up autoneg implementations. that's like 3 decades ago
tho and just history now.

autoneg is absolutely mandantory on GigE and above and negotiates more
than just speed & duplex.

having one side hand-set and one on autoneg is the worst possible
combo, that almost certainly leads to duplex mismatch.
