Hi,
I am using linux 2.4.20-8 smp kernel on a dual processor Xeon 2GHz
processor with 4 Intel PRO 1000 MT Desktop adapters. I am using latest
version of e1000 drivers with NAPI enabled. I am facing a problem. I want
to read packets from one NIC and send them to one of the other three NICs
based on some hash function. When I try this experiment at high speeds
(>250 Mbps) using either raw sockets (application level programming) or by
writing a kernel module for IP_PREROUTING_HOOK, my system is hanging. Can any one please help me out
by telling some possible reason for this and how to get rid of this.
Is it OK to use 4 NICs simultaneously at such high speeds.
Thanks in advance,
Ananth.
