[ovs-dev] [PATCH v2] dpif-netdev: Remove PMD latency on seq_mutex

2016-05-04 Thread Flavio Leitner
The PMD thread needs to keep processing RX queues in order to achieve maximum throughput. It also needs to sweep emc cache and quiesce which use seq_mutex. That mutex can eventually block the PMD thread causing latency spikes and affecting the throughput. Since there is no requirement for running
