while examing PR kern/23782 I've noticed an intesting detail. Here is
what the result of auto negotiation between an Intel i82540EM and
my 3Com GbE switch:

        media: Ethernet autoselect (1000baseT full-duplex)

And here is what the Intel i82547EI detects:

        media: Ethernet autoselect (1000baseT full-duplex,flowcontrol,rxpause,tx

Is it possible that auto negotiation is broken somehow? I've tried to
use manual configuration with the i82547EI but it completely killed
the link.

	Kind regards
