Subject: Problem in multi-queue receiving
Date: Sat, 9 Aug 2014 11:59:24 -0400	[thread overview]
Message-ID: <CACKSPmeriwphHnR=1kqOC6+5S0EqWDbK7VHMXEccca55iSDHFg@mail.gmail.com> (raw)

Hi there,

I have a problem for multi-queue receiving.

For a specific application, I am not using the lcore abstractions in DPDK.
I launch rx and tx threads seperately. For one port with N queues, I
launched N rx threads and N tx threads, with each thread in charge of
receiving or sending only one queue.

The tx threads work on their own queues well. However, all received packets
only go to queue 0 rx thread, and other rx threads receive nothing.

My code is at :
https://github.com/kay21s/dpdk/blob/master/examples/pthread/main.c
It has a default NUM_QUEUE=2, which means port 0 is configured with 2
queues, and 2 rx threads and 2 tx threads are launched.
Is there any problem in my implementation? or DPDK does not support it?

Thanks a lot!
Kai
