From bb7189dc78d643b2707483763664a02ac017ac59 Mon Sep 17 00:00:00 2001 From: Qianqian Xie Date: Tue, 21 Jun 2016 11:56:29 +0800 Subject: [PATCH] net: hns: fix the wrong speed for bond For debug-ports,there are two non-synchronized processes: Speed-Auto-Negotiation and Link-Update-Status. The two processes are towed by two different state machines. Bond reads the speed when link up, but the speed maybe not update the right value at that time.That make for bond's wrong speed. Thus only one state machine should be used and if phy_state_machine is used, it does not need to do hns_nic_update_link_status().
