I think I'm hitting some compiler related issue here...

The kernel with the patch I sent applied is working pretty fine
even with "generic-receive-offload" ON for my tg3 nic...

What is the big difference there?

Or do we need to dig into the object files now? Because that's
what's too scary for me...

P.S. The compiler I am using is :
