virtio: add default Tx configuration
When I tried to launch test-pmd on KVM guest of Fedora21, I got following error:
Configuring Port 0 (socket 0)
Fail to configure port 0 tx queues
EAL: Error - exiting with code: 1
Cause: Start ports failed
I found that the error caused here, and actual error message was
"TX checksum offload not supported".
This patch adds default_txconf on virtio pmd, to avoid the error.
