Under low rate traffic conditions, there can be 2 issues.
(1) Packets potentially can get stuck in the intermediate queue.
(2) Latency of the packets can increase significantly due to
buffering in intermediate queue.
This commit handles the (1) issue by flushing the tx port queues from
This commit refactors the __netdev_dpdk_vhost_send() and enables
intermediate queue where in the packets are buffered till the threshold

This commit introduces netdev_dpdk_eth_tx_queue() function that
implements intermediate queue and packet buffering. The packets get
buffered till the threshold 'INTERIM_QUEUE_BURST_THRESHOLD[32] is
reached and eventually gets transmitted.
To handle the case(eg: ping) where packets are sent at low
Add netdev_txq_flush(), that flush packets on a queue. This is needed
to transmit packets on the intermediate queue.

Add netdev_dpdk_vhost_txq_flush(), that flushes packets on vHost User
port queues. Also add netdev_dpdk_vhost_tx_burst() function that
uses rte_vhost_enqueue_burst() to enqueue burst of packets on vHost User
ports.

This commit adds netdev_dpdk_txq_flush() function. If there are
any packets waiting in the queue, they are transmitted instantly
using the rte_eth_tx_burst function. In XPS enabled case, lock is
taken on the tx queue before flushing the queue.

Hello Ben,
Can you please check if the changes look good and apply this patch to the
master.
The Keepalive patch series has a dependency on this patch (using few of the
below APIs). I can send the first non-RFC version of KA patch series only if
this patch is in.
Regards,
Bhanuprakash.

Previously if there is no available (non-isolated) pmd on the numa node
for a port then the port is not polled at all. This can result in a
non-operational system until such time as nics are physically
repositioned. It is preferable to operate with a pmd on the 'wrong' numa
node albeit with lower p
Patch is marked as RFC because DPDK 17.05.1 is not yet
published.
Upgrading to DPDK 17.05.1 stable release adds new
significant features relevant to OVS, including,
but not limited to:
- tun/tap PMD,
- VFIO hotplug support,
- Generic flow API.
Following changes are applied:
