Linux 2.2.14 and FA310TA cards

[Chris Martin]

------- Start of forwarded message -------
I have two FA310TX cards, one in a 150 MHz Pentium machine and the
other in a 600 MHz dual Pentium III machine linked by an FE104 hub (a
Netgear FB104 starter kit).

Both machines run Linux 2.2.14.

No problems were reported when I tested the connection under DOS using
the DIAG.EXE on the diagnostic disk.

I also ran the tests with each of the machines being master (with the
other slave) in turn with no problems reported.

However, pinging the fast machine from the slow machine when both were
running Linux shows, typically,

  53 packets transmitted, 21 packets received, 60% packet loss
  round-trip min/avg/max = 0.3/0.3/0.3 ms

While pinging the slow machine from the fast machine shows

  51 packets transmitted, 23 packets received, +10 corrupted, 54% packet loss
  round-trip min/avg/max = 0.2/0.2/0.2 ms

The corrupted packets show an output like

64 bytes from 192.168.1.1: icmp_seq=40 ttl=255 time=0.2 ms (BAD CHECKSUM!)
wrong data byte #29 should be 0x1d but was 0x1c
	84 6e 4 39 cc 39 f 0 8 9 a b c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1c 1c 1c 
	1d 1e 1f 20 21 22 20 25 26 27 24 29 2a 2b 28 2d 

I originally used the driver (tulip.c) from the kernel tarball, this
was 0.91g-ppc, I then replaced it in the kernel source with the driver
supplied on the Netgear driver/diagnostic disk, 0.89K, and then
downloaded the development driver, 0.91g.

Finally I downloaded and installed 0.92 having set up the kernel to
load tulip.o as a module and overwriting it with the modules from
netdriver-2.0-2.src.rpm.

The driver at present in use announces itself (on the fast machine) as

 tulip.c:v0.92 4/17/2000  Written by Donald Becker <becker@scyld.com>

 eth0:  MII transceiver #1 config 3000 status 7829 advertising 01e1. 

and on the slow machine as

 tulip.c:v0.92 4/17/2000  Written by Donald Becker <becker@scyld.com> 
   http://www.scyld.com/network/tulip.html 
 eth0: Lite-On 82c168 PNIC rev 32 at 0xc4820000, 00:A0:CC:5D:59:FB, IRQ 10. 
 eth0:  MII transceiver #1 config 3000 status 7829 advertising 01e1. 

Netgear support say they only know Windows and ask if the cards are in
a bus mastering slot.

Is it worth continuing with these cards or should I send them back and
get Vortex cards instead?
