Hi all,
Finally, a _real_ Linux problem! It's taken me months to get one!
The box is a bridging firewall, with a custom compiled kernel. I've
done this configuration loads of times, but not with these NICs.
Here's some pertinent info:
00:0a.0 Ethernet controller: National Semiconductor Corporation DP83815
(MacPhyter) Ethernet Controller
00:0b.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900
10/100 Ethernet (rev 02)
The natsemi driver is built as a module, and the SiS900 driver is
compiled into the kernel.
The problem is that clients are finding WAN access very slow. Here's
why - we're dropping packets on eth0:
br0 Link encap:Ethernet HWaddr 00:06:4F:03:FE:73

I'm ashamed to say that I don't know how to see which card is eth0. I'm
not on site, and I'd rather not go there just for this. I'm guessing
it's the one with the lower PCI id (the natsemi)?
APIC is compiled into the kernel, and I've heard that removing it
might help. Anyone have any advice? (Running 2.4.18.)
