This is the first part of XPS patch-set which contains generic fixes not
directly connected with XPS or manual pinning but required by them.
First patch allows to reconfigure number of queues for DPDK vHost
in runtime according to settings from connected virtio device.
Second patch adds new option 'n_txq' for dummy-pmd. It will be used
in the future patches.
Version 5:
* 'dpif-netdev: Move setting of queue number to netdev layer.'
splitted in 2 patches because changes are not really
connected now.
* 'set_tx_multiq()' returned to configure 'n_txq' from the
datapath layer for ETH ports.
Version 4:
* Dropped already applied patch
"netdev-dpdk: Use instant sending instead of queueing of packets."
* Merged fixup from previous version:
http://openvswitch.org/pipermail/dev/2016-June/073906.html
It adds few comments and reduces number of queues to poll after
virtio disconnection by reconfiguration with 1 queue pair requested.
* rebased on current master
Ilya Maximets (2):
netdev-dpdk: Obtain number of queues for vhost ports from attached
virtio.
netdev-dummy: Add n_txq option.
