Subject: [dpdk-dev] [PATCH 13/52] i40e/base: Add a workaround to drop all flow control frames
Date: Sun, 6 Sep 2015 15:11:27 +0800 [thread overview]
Message-ID: <1441523526-26202-14-git-send-email-jingjing.wu@intel.com> (raw)
In-Reply-To: <1441523526-26202-1-git-send-email-jingjing.wu@intel.com>
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.
