Hi there
Thanks for the reply.
I'm using the script and binding queue per cpu. For RX this situation is
great.
The problem is with TX.
I'm working on a firewall machine and the inbound packets are sometimes
handled and transmitted from other CPUs that are not in the RX range.
For example inbound RX packet on rx_queue 0 on CPU 0 is processed on CPU 20
which is sent on tx_queue 20.
Another example is xmit on CPU 65, which is sent to tx_queue 1 (i think)
because max TX queues for ixgbe is 64.
