[tulip] lag problems with Linksys 10/100

[Mihai Badoiu]

I'm using a 10/100 Linksys-tulip chipset with RedHat 6.2, kernel 2.2.18. I have the
latest drivers. The problem is that the network lags from time to time.
It's something like this:

64 bytes from ZAMOLXIS.MIT.EDU (18.244.1.85): icmp_seq=941 ttl=255 time=2.0 ms
64 bytes from ZAMOLXIS.MIT.EDU (18.244.1.85): icmp_seq=942 ttl=255 time=1.6 ms

I have tested 2 other network cards that have a rtl8139 chip and I get the same problem.
Any ideas what can be wrong? Is it possible that the pci-scan driver bugs? I have an
Athlon 1Gz on a KT7 motherboard.

thanks,
