I thought UD has only a single-packet window in the qp context. >There isn't much uniformity about this in drivers/net. > >Unfortunately, making the ring sizes settable per-interface leads to a >lot of ugly option handling code.

Has anyone instrumented it for overruns and drops, and watched it under load? That would tell us what to tweak. I dunno, it's probably deferrable (with Shirley's queue changes) as long as there's a way to diagnose it later. Constants are pretty much never correct in networking code. And module parameters are darn close to being constants.
