Issue Description

 The duplex mode changed at Ethernet port of AR2830 does not take effect. 

Alarm Information

Port negotiation.

Handling Process

Change the working mode of the peer to full duplex.

Root Cause

AR series routers need to negotiate the duplex mode with the peer when their Ethernet ports are in forced full duplex; if the peer port works in half duplex, our products will work in half duplex ultimately, and the forced full duplex does not take effect.
