I refuse any further comments on this ;-)

thanks. The module compiles fine now and probes the nics successfully:

gate# kldload ./if_re.ko
re0: <RealTek 8139C+ 10/100BaseTX> port 0xdc00-0xdcff mem 0xe3400000-0xe34000ff irq 11 at device 9.0 on pci0
re0: Ethernet address: 00:90:fb:04:1b:31
[... re1, re2, re3, re4 ...]

The appendant PHY:

miibus0: <MII bus> on re0
rlphy0: <RealTek internal media interface> on miibus0
rlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

ifconfig still gives no info about the media types:

gate# ifconfig re0
re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:90:fb:04:1b:31
        media: Ethernet autoselect (none)

The original driver v 1.24 with the (deactivated) old diagnostic
code works quite ok (despite of teh misleading / missing ifconfig
output for the media). The patched driver from your driver doesn't
work anymore; all attempts to send or receive packets fail. 

Currently I can't tell you anything about the concrete link state
of the interface. The box and the (unmanaged) switch are 36 km away
from here.

It's possible, that I get there tomorrow or on monday at the latest.

If you need any further information beforehand, just tell me  ...
