I have found the ring a bit small when trying to cope with many small
buffers, but it's workload and system dependent so it should probably be
set on a case by case basis.

Are there any disadvantages to increasing the txqueue?

What ever happened to the new netchannel stuff? Did that promise larger
rings?
