From a30b016808e214c6864ad579ef867b3fe0a314f8 Mon Sep 17 00:00:00 2001 From: Aviv Heller Date: Tue, 5 Jul 2016 12:09:47 +0300 Subject: [PATCH] bonding: fix enslavement slave link notifications Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic.
