...moving to production. Googling, I see there is some history of e100e driver having issues, and I'm wondering if it could be related. Does anyone have any thoughts on where to do with it, as I'm assuming it will hang again later.

Hi, I am using iproute2 to setup fowarding, adding routes like "ip route add 192.168.1.3 via 192.168.1.2" I was wondering where in the kernel I can insert probabilistic packet loss only for forwarded packets? So that for instance I can drop 5% of all forwarded packets? I don''t need help with the actual code, just need help finding where to insert this code :) Thanks! George
