From: Wenjun Wu Date: Wed, 2 Jun 2021 02:24:41 +0000 (+0800) Subject: net/iavf: support RSS for GRE tunnel packet X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2e3dbc80cc012f11799c7eda866e1168dadb5032;p=dpdk.git net/iavf: support RSS for GRE tunnel packet Support AVF RSS for inner header of GRE tunnel packet. It supports RSS based on fields inner IP src + dst address and TCP/UDP src + dst port.
