From bb3daa4a5960cd9d39bad88679fcf587b456c05d Mon Sep 17 00:00:00 2001 From: PJ Waskiewicz Date: Wed, 25 Mar 2009 22:10:42 +0000 Subject: ixgbe: Allow Priority Flow Control settings to survive a device reset When changing DCB parameters, ixgbe needs to have the MAC reset. The way the flow control code is setup today, PFC will be disabled on a reset. This patch adds a new flow control type for PFC, and then has the netlink layer take care of toggling which type of flow control to enable.
