From f4314e815e87b4ab1c9b1115dd5853cd20ca999c Mon Sep 17 00:00:00 2001 From: Don Skidmore Date: Sun, 21 Dec 2008 20:10:29 -0800 Subject: net: add DCNA attribute to the BCN interface for DCB Adds the Backward Congestion Notification Address (BCNA) attribute to the Backward Congestion Notification (BCN) interface for Data Center Bridging (DCB), which was missing. Receive the BCNA attribute in the ixgbe driver. The BCNA attribute is for a switch to inform the endstation about the physical port identification in order to support BCN on aggregated links.
