>Description:
The de drivers does not work at 100Mbits for Compex TX100-PCI cards.
These cards are based on DEC21140-AC (read from chip).
The cold start condition for these cards is 100Mbits unles they
are conected to 10Mbits HUB.
On cold starting a FreeBSD machine with one of these cards conected
to a 100Mbits HUB the 100M led is on untill the card is recognized
by the de driver. The following message is printed:
de0 <Digital DC21140 Fast Ethernet> rev 32 int a irq 10 on pci0:8
de0: DC21140 [10-100Mb/s] pass 2.0 Ethernet address 00:48:54:00:01:c5
de0: enabling 100baseTX UTP port
then the 100M led turns off and the 10M turns on.
The same behaviour occurs for two computers connected through a Cross Connect
Cable but the card goes to an undetermined state, nor 10M or 100M speeds
are set and the two computers can't comunicate.
ifconfig'ing -link2 both sides make the computers comunicate at 10M but
it seems there is no way to make the card to run at 100M.
HUBS and cables were triple checked before this send-pr
>How-To-Repeat:
Just install Compex TX100 cards on 2.1.0/2.1.5/2.1.6 and try
to run at 100M
