[tulip] Multiple detection? and more troubles

tasc> I've succeeding in linking 0.92 into a 2.2.10 kernel (I was previously using

tasc> and so sets up eth0 through eth7!
At me the same problem with a card cnet on the chip davicom 9102.
[root@linux admin]# grep -i davicom /var/log/dmesg
eth1: Davicom DM9102 rev 49 at 0xc8002000, 00:00:AD:72:01:62, IRQ 10.
eth2: Davicom DM9102 rev 49 at 0xc8004000, 00:00:AD:72:01:62, IRQ 10.
eth3: Davicom DM9102 rev 49 at 0xc8006000, 00:00:AD:72:01:62, IRQ 10.
eth4: Davicom DM9102 rev 49 at 0xc8008000, 00:00:AD:72:01:62, IRQ 10.
eth5: Davicom DM9102 rev 49 at 0xc800a000, 00:00:AD:72:01:62, IRQ 10.
eth6: Davicom DM9102 rev 49 at 0xc800c000, 00:00:AD:72:01:62, IRQ 10.
eth7: Davicom DM9102 rev 49 at 0xc800e000, 00:00:AD:72:01:62, IRQ 10.
(eth0 is 3com 590)
It is unpleasant to that those network cards, which search goes the
ambassador tulip (i.e. 3com 509), are not automatically detected.
Other problem - speed of drivers for linux. I have a file server NW
4.1 with a network card 3com 905 and machine with a network card cnet
connected to server cross-over by a cable. For testing the copying
from server of a file by the size 49Mb to /dev/null was used (to avoid
reading from a disk all repeated three times and got out minimal
value). Under linux it has appeared 17 (seventeen!!!!) seconds. Under
win'98 5 (five) seconds.
And last - from time to time on the console is given out the message "
eth1: Transmit error ". Such impression, that it occurs in some
seconds after network activity.
Linux: RH 6.0
PS: with network cards cnet there is a driver dmfe.c. Somebody has
tried to use it?
dmfe.c: Version 1.27 10/08/1999
A CNet PRO200 DM9102(A)/DM9132/DM9801 fast ethernet driver
