[ovs-dev] [PATCH v8 0/2] dpif-netdev: proper tx queue id

[Ilya Maximets]

Note: First patch of this series may be applied separately
      to fix existing problem with mapping of TX queues.

version 8:
	* Nobody wants to review huge architectural patches.
	  So, I divided it into two. First patch fixes original
	  problem with unexpected mapping of TX queues.
	  Second patch adds new infrastructure for TX queue
	  management. Details are in commit messages.
	* Fixed calculation of global_index on port deletion.

version 7:
	* rebased on current master
	* My comment for v6 that there is a race for total number of
	  threads was wrong. So, patch actually the same as v6.

version 6:
	* fixed assigning same txq to multiple pmd threads on different
	  NUMA sockets.
	* Changed logic of txq distribution in pmd_load_queues().
version 5:
	* txqs 0 from ports of non-pmd netdevs added to all pmd threads

version 4:
	* fixed distribution of tx queues if multiqueue is not supported

version 3:
	* fixed failing of unit tests by adding tx queues of non
	  pmd devices to non pmd thread. (they haven't been used by any thread)
	* pmd_flush_tx_queues --> dp_netdev_pmd_detach_tx_queues
	* function names changed to dp_netdev_*
	* dp_netdev_pmd_lookup_txq now looks by port_no.
	* removed unnecessary dp_netdev_lookup_port in dp_execute_cb
	  for OVS_ACTION_ATTR_OUTPUT.
	* refactoring

Ilya Maximets (2):
  dpif-netdev: unique and sequential tx_qids.
  dpif-netdev: Add per pmd cmap of available tx queues.
