FS#616 - Ethernet port fails to receive traffic if traffic was received during init

[openwrt-bot]

syoder89:

Symptoms: Fails to receive address via DHCP on WAN port
Board: WPJ558
Lede ver: 92b5b36 (Mar 7, 2017)
Steps to reproduce: ping -f wan_port_ip from another machine, reboot WPJ558

I have tracked the problem down to commit lede-project/source@94e4ee5 , more specifically enabling flow control on ports 1-5.

The problem goes away if I comment out line 693 from the patch:

•   t |= AR8216_PORT_STATUS_FLOW_CONTROL;
  

Funny how this caused the problem it was trying to solve...
