Hi all,

I have an AlphaStation 500/266, which I'm putting to some more
serious use currently. It has two DEC NICs in it:

NetBSD 1.6ZF (MAAILMA) #0: Thu Nov 27 20:13:57 EET 2003
tlp0 at pci0 dev 6 function 0: DECchip 21040 Ethernet, pass 2.4
tlp0: interrupting at kn20aa irq 13
tlp0: Ethernet address 00:00:f8:21:9d:b2
tlp0: 10baseT, 10baseT-FDX, 10base5, manual
tlp1 at pci0 dev 12 function 0: DECchip 21140 Ethernet, pass 1.2
tlp1: interrupting at kn20aa irq 4
tlp1: DEC DE500-XA, Ethernet address 00:00:f8:30:28:35
tlp1: 10baseT, 100baseTX, 100baseTX-FDX, 10baseT-FDX

There are a few problems: tlp1 doesn't support Nway, and
100baseTX-FDX doesn't work. I get a lot of MII/CRC errors.
100baseTX works quite nicely but I have a feeling it has some
odd botches too (other computer on the switch is using 100baseTX-FDX).

And tlp0 shows this every now and then:

tlp0: receive error: MII error
tlp0: receive error: dribbling bit
tlp0: receive error: CRC error

But this doesn't seem to have any ill effects, and happens pretty

I was just wondering whether there might be any difference
or advantage in using de driver or tlp? (Or might it be sensible
to replace tlp1 with a spare rtk NIC?)
