Manual pinning API was discussed here:
http://openvswitch.org/pipermail/dev/2016-July/074674.html
Version 5:
* XPS and Manual pinning back together.
* Dropped already applied patches
* All fixups from pinning v3 merged.
* XPS doesn't work if we have enough TX queues
* Affinity parser changed to reuse existing code
* 'needs_locking' logic moved to dpif-netdev.
Old XPS log:
Version 4:
* Dropped rwlock related patches.
* Added pointer from 'struct tx_port' to 'struct dp_netdev_port'
to avoid locking of 'dp->ports'. This works because as long as
a port is in a pmd thread's tx_port cache it cannot be deleted
from the datapath.
* Added 'now' parameter to 'dp_netdev_execute_actions()' to pass
current time to XPS functions. This needed to avoid using
'last_cycles' that is always 0 without DPDK.
* Fixed tx queue ids cleanup on PMD thread deletion.
Version 3:
* Dropped already applied changes.
* fat-rwlock used instead of port_mutex.
* revalidation of 'non-pmd' thread's tx queues added to
'dpif_netdev_run' to make it faster.
Ilya Maximets (4):
dpif-netdev: XPS (Transmit Packet Steering) implementation.
bridge: Pass interface's configuration to datapath.
dpif-netdev: Add reconfiguration request to dp_netdev.
dpif-netdev: Introduce pmd-rxq-affinity.
