::No no no. *You* are the one who's supposed to make the comments.

::What kind of hub/switch/whatever is the card connected to? You know,

Hello Bill,
I'm sorry about that. Here's some information that I can gather:
1. The Intel 21143 chips is intergrated in NEC VersaPro NoteBook PC.
No LED to indicate the network activity are available.
2. It is connected to 10BaseT Hub (HP 28688B) at half duplex.
3. dmesg output:
dc0: <Intel 21143 10/100BaseTX> port 0xe880-0xe8ff mem 0xfebfec00-0xfebfefff irq 5 at device 5.0 on pci0
dc0: Ethernet address: 00:00:4c:73:16:8a
miibus0: <MII bus> on dc0
dcphy0: <Intel 21143 NWAY media interface> on miibus0
dcphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
4. When connection's ok (w/ if_dc.c: rev 1.20):
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 133.253.157.145 netmask 0xffffff00 broadcast 133.253.157.255
inet6 fe80::200:4cff:fe73:168a%dc0 prefixlen 64 scopeid 0x1
ether 00:00:4c:73:16:8a
media: autoselect (10baseT/UTP) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> none
5. When connection's no good (w/ if_dc.c: rev 1.21):
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 133.253.157.145 netmask 0xffffff00 broadcast 133.253.157.255
inet6 fe80::200:4cff:fe73:168a%dc0 prefixlen 64 scopeid 0x1
ether 00:00:4c:73:16:8a
media: autoselect (none) status: no carrier
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> none
It seems that there's no negotiation done with the Hub at all.
Hope this helps,
Haro
