[dpdk-dev] Problems running netvsc multiq

[Mohammed Gamal]

Hi All,
I am having the following errors when I run testpmd with the netvsc
driver and --txq 2 and --rxq 2 options:

testpmd: create a new mbuf pool <mbuf_pool_socket_0>: n=155456,
size=2176, socket=0
testpmd: preferred mempool ops selected: ring_mp_mc
Configuring Port 0 (socket 0)

EAL: Error - exiting with code: 1
  Cause: Start ports failed

Multiq support was enabled and kernel module was loaded. The full
command line was:
./testpmd -l 0-1 -n 2 --log-level=8 --log-level='pmd.*,8' --log-
level='bus.vmbus,8' -- --port-topology=chained --forward-mode=rxonly --
stats-period 1 --eth-peer=0,00:15:5d:1e:20:c0 --txq 2 --rxq 2

I am running latest upstream kernel from the Linus tree and latest DPDK
upstream from git.dpdk.org.

Could you also reproduce this? If not, what could I be misssing?

Regards,
Mohammed
