Greetings
Some more info regarding my overrun problem with an LNE100TX
when used in a Linux firewall:
It was suggested that a high overrun count indicates tulip.c wasn't compiled
for SMP correctly - the gcc command line appears to be correct however:
gcc -D__KERNEL__ -I/ex/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -D__SMP__ -pipe -fno-strength-reduce -m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2 -DCPU=586 -c -o tulip.o tulip.c
and SMP_CHECK is defined in tulip.c
In case SMP is an issue, I compiled a uniprocessor kernel. The data
rate when FTPing from NT (ako->firewall) actually has increased somewhat,
although I still see approximately 10% of the packet count as overruns:
eth0 Link encap:Ethernet HWaddr 00:A0:CC:36:BD:13
inet addr:192.168.0.1 Bcast:127.255.255.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:23257 errors:1845 dropped:0 overruns:1845 frame:0
TX packets:17174 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:9 Base address:0xe800
As before (when in SMP), the overruns are only on the receiving side. Any
suggestions would be greatly appreciated. Thanks.
Setup:
ako: Dual PII-450, running NT4 SP6 or Linux 2.2.14 (SMP), Intel EtherExpress
10/100 on the motherboard
firewall: Dual P5-90 running Linux 2.2.14 with firewall options set,
LinkSys LNE100TX 10/100 LAN Card
Machines are connected to each other via a category 5 crossover cable.
