Hi ALL,
We have developed a custom board mother board based on
MPC8541 processor running Linux 2.6.11.
In our system, most of the ingress UDP packets are retransmitted
with one modification to data portion of the packet (one byte). As you
see there are many copy overhead due to copy from system to userland
and vise versa which has impacted our system performance.
Is there a zero-copy support for TSEC
to eliminate the buffer copy from kernel to userland and vise versa?
Are there any other technique that we need to do to eliminate packet
coping?
Many thanks in advance,
Bizhan
