From 0eb3aa9bab20217fb42244ccdcb5bf8a002f504c Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 20 Nov 2008 21:09:23 -0800 Subject: DCB: Add interface to query the state of PFC feature. Adds a netlink interface for Data Center Bridging (DCB) to get and set the enable state of the Priority Flow Control (PFC) feature. Primarily, this is a way to turn off PFC in the driver while DCB remains enabled.
