The first thing to try would be to use sane allocation sizes

Thanks a lot. This patch already decreased the CPU usage for ctevtest
from 85% to 44%. Sweet...
I just rerun the test. The 85% CPU usage was with 1700pps and 44% with
1500pps. The wireless channel does not provide the same performance all
the time and I did not pay attention to the packet rate.
Without the allocation patch and 1500pps the CPU usage is 56%. But 10%
less is still quite nice.
