[ovs-dev] [PATCH] Improve MPLSoGRE performance by reducing EMC hash collisions.

2019-08-13 Thread Nitin Katiyar
When a packet is received, the RSS hash is calculated if it is not already available. The Exact Match Cache (EMC) entry is then looked up using this RSS hash. When a MPLSoGRE encapsulated packet is received, the GRE header is popped, the RSS hash is invalidated and the packet is recirculated for
