Date: Tue, 14 Jan 2014 18:54:08 +0800 From: Ding Tianhong <dingtianhong@...wei.com> To: Jay Vosburgh <fubar@...ibm.com>, Veaceslav Falico <vfalico@...hat.com>, "David S. Miller" <davem@...emloft.net>, Netdev <netdev@...r.kernel.org> Subject: [PATCH net-next v2.1 1/3] bonding: update the primary slave when changing slave's name If the slave's name changed, and the bond params primary is exist, the bond should deal with the situation in two ways: 1) If the slave was the primary slave yet, clean the primary slave and reselect active slave. 2) If the slave's new name is as same as bond primary, set the slave as primary slave and reselect active slave. Thanks for Veaceslav's suggestion.
