Hi, I've been using two 3c905B cards (one on an SMP linux server and one
on a single processor workstation) connected with a single cord.
Naturally I want to run 100Mb/s full duplex and doing that i've
encountered the following problems:
* The last driver i've tried that was able to correctly set the 100Mb/s
transciever through options (options=3D4 full_duplex=3D1) was the 0.99E
driver. I've also tried the G, H, H-WOL, Kb and L drivers. None of them
works. Mostly the cards fall back to 10Mb/s, but some connecting and
disconnecting the TP cable during bootup _may_ trigger a 100Mb/s
connection.
* To have a 100Mb/s connection it is sufficient to run the 0.99E driver
on the server. The workstation seems to auto-sense the forced 100Mb/s
connection.
So up to now I've been able to run my connection at 100Mb/s by replacing
the driver when a new kernel was installed. This worked OK up to and
including kernel 2.2.2
*However, with Red Hat 6.0, kernel 2.2.5 was supplied together with the
0.99H driver. With this kernel the 0.99E driver yielded an
ff:ff:ff:ff:ff:ff station address and transmitted (according to
ifconfig) ten-thousands of packets in an amazingly short time.
*With the 0.99H driver, no connection was established at all.
* Trying desperately to connect the server card to a cable-tv modem (a
10 Mb/s half duplex connection that works flawlessly with a NE2000
compatible card in the same server), any options whatsoever supplied to
the driver at boot time will completely inhibit transmission and
reception of packets (again according to ifconfig)
* If the driver is started with no options, some activity is observed
and packets are received and transmitted according to ifconfig:
eth0 Link encap:Ethernet HWaddr 00:10:4B:69:FC:88
inet addr:172.22.4.27 Bcast:172.22.7.255 Mask:255.255.252.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:391 errors:0 dropped:0 overruns:0 frame:0
TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:10 Base address:0xd400
however, it is impossible to establish a connection using ping,
telnet or whatever. (It works with the NE2000 card, however).
* A similar 3c905B card at work works flawlessly connected to a 100Mb/s
full duplex switch with kernel 2.2.5 and the 0.99H driver. (I'm not
completely sure that the speed is really set through the options and not
by auto-sensing,though)
So my questions are:
1: Why doesn't my cards respond to the speed chosen with "options=3D4"
except with the 0.99E driver?
2: Why doesn't my cards work at all with the 0.99Hdriver and kernel
2.2.5? particularly when ifconfig reports packets transmitted and
received ?
Any help would be _GREATLY_ appreciated.
I'm attaching the output of vortex-diag and the output of the driver at
boot time.
