This patch corrects an omission from the following commit: commit f0c76d61779b153dbfb955db3f144c62d02173c2 Author: Jay Vosburgh <fubar@us.ibm.com> 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.
