Mine doesn't (what are "orange bits"?), at least not with my HP-4000m so
far as I can recall.

	tlp1 at pci1 dev 3 function 0: DECchip 21143 Ethernet, pass 3.0
	tlp1: interrupting at kn300 irq 12
	tlp1: DEC DE500-BA, Ethernet address 08:00:2b:c3:50:d7
	tlp1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

Anyway I have to have it set up with:

$ cat /etc/ifconfig.tlp1
up
204.92.254.24 netmask 0xffffff00 media 100baseTX mediaopt full-duplex
[[... and some aliases ...]]


and of course I've got the switch port config locked too (things cannot
work properly if one side tries to use auto-negotiation and the other
side has it turned off, especially if the side that turned it off has
also set full-duplex mode).


In my AS4100 5/400 it is not very fast at sending though (this is with
the fastest machine currently running on my network):

# ping -s 1490 -f once

It does a heck of a lot better at receiving though:
