From 17d04500e2528217de5fe967599f98ee84348a9c Mon Sep 17 00:00:00 2001 From: Jay Vosburgh Date: Wed, 18 Mar 2009 18:38:25 -0700 Subject: [PATCH] bonding: Fix updating of speed/duplex changes This patch corrects an omission from the following commit: commit f0c76d61779b153dbfb955db3f144c62d02173c2 Author: Jay Vosburgh Date: Wed Jul 2 18:21:58 2008 -0700 bonding: refactor mii monitor The un-refactored code checked the link speed and duplex of every slave on every pass; the refactored code did not do so. The 802.3ad and balance-alb/tlb modes utilize the speed and duplex information, and require it to be kept up to date. This patch adds a notifier check to perform the appropriate updating when the slave device speed changes. Signed-off-by: Jay Vosburgh Signed-off-by: David S.
