From e5c9ed3bbd4afb4e3b469eaf2ca556d3f8420286 Mon Sep 17 00:00:00 2001 From: Haiyue Wang Date: Tue, 12 Jan 2021 16:13:00 +0800 Subject: [PATCH] net/iavf: support CRC strip disabling The VF will check the PF's CRC strip capability firstly, then set the 'CRC strip disable' value in the queue configuration according to the RX CRC offload setting.
