[dpdk-dev] RSS granularity configuration

From: dev [mailto:dev-bounces@dpdk.org] On Behalf Of Krishna, Vinod

Hi Vinod,

Could you provide more information or probably an example of any "non-standard" packets?

Regards,
Andrey

Message-ID: <1443078497-20602-1-git-send-email-helin.zhang@intel.com>

The default fields of a received packet are loaded from firmware, which cannot be modified even users want to use different fields for RSS or filtering. Here adds a workaround to open more flexibilities of selecting packet fields for hash calculation or flow director to users. It also includes the modifications in testpmd to support the testing.

v2 changes:
Solved the compilation issues.

v3 changes:
Support selecting more input set fields.
