hello,
i'm trying to set up 2.2-960612-SNAP as router using 3C590 PCI
cards, and i'm having a number of problems. the hardware platform
is a dell dimension XPS P133. the network performance of this setup
is horrendous when it decides to work at all. for small amounts of
data, it's actually pretty good (hard to measure for such small amounts,
but on the order of what i'd expect), but for anything over about 1kB
or maybe 1536 bytes, it's chancy as to whether it works at all. i'm
using ftp to do most of my testing, both as ftp hosted on this machine
and as ftp using this machine as a router.
when i boot, the message i get on the ethernet cards is:
vx0 <3Com 3c590 EtherLink III PCI> rev 0 int a irq 10 on pci0:15
aui/bnc/utp[*BNC*] address 00:a0:24:59:da:e1
Warning! Defective early revision adapter!
vx1 <3Com 3c590 EtherLink III PCI> rev 0 int a irq 11 on pci0:16
aui/bnc/utp[*BNC*] address 00:a0:24:72:eb:ba
Warning! Defective early revision adapter!
i looked in the source and found:
/*
* Check for receive overrun anomaly in the first revision of the
* adapters.
*/
if(!(get_e(unit, EEPROM_SOFT_INFO_2) & NO_RX_OVN_ANOMALY)) {
printf("Warning! Defective early revision adapter!\n");
}
but these cards were purchased pretty recently.
does anyone know where to get cards which do not suffer from this anomaly?
does anyone know why performance on dos based machines aren't suffering
from the same problems?
does anyone know if this is to be fixed before the main release of 2.2?
does anyone have good experiences either with these cards (and what are
you doing right that i'm doing wrong) or with other pci ethernet cards
(i've heard that the SMC EtherPower cards are pretty good)?
i'd appreciate any information and will answer further questions. thanks
markus
