From 031ae4deb095a1f18a842740459c5ae184ec931c Mon Sep 17 00:00:00 2001 From: Jay Vosburgh Date: Wed, 13 Jun 2007 22:11:34 -0700 Subject: bonding: Fix 802.3ad no carrier on "no partner found" instance Modify carrier state determination for 802.3ad mode to comply with section 43.3.9 of IEEE 802.3, which requires that "Links that are not successful candidates for aggregation (e.g., links that are attached to other devices that cannot perform aggregation or links that have been manually configured to be non-aggregatable) are enabled to operate as individual IEEE 802.3 links." Bug reported by Laurent Chavey . This patch is an updated version of his patch that changes the wording of commentary and adds an update to the driver version.
