From e7358f54a3954df16d4f87e3cad35063f1c17de5 Mon Sep 17 00:00:00 2001 From: Anjali Singhai Jain Date: Thu, 1 Oct 2015 14:37:34 -0400 Subject: i40e/i40evf: Add a workaround to drop all flow control frames This patch adds a workaround to drop any flow control frames from being transmitted from any VSI. FW can still send flow control frames if flow control is enabled. With this patch in place a malicious VF cannot send flow control or PFC packets out on the wire.
