Details - Hi - 

I am on the R8000 and have seen this issue across all builds I've tried for the last two months, and as far as I know this has been present forever. The device is connected on IPv4 with VLAN tagging to my ISP using PPPOE. The packet loss being seen is from a hardwired device, and this packet loss can be replicated on any port and with other devices. Attached is a PingPlotter output showing the packet loss. I tried disabling the syn rule in iptables, as I initially suspected that might be the cause. Right now, I am running: 
Model	Netgear R8000 (BCM4709)
Firmware Version	LEDE Reboot r1597 / LuCI Master (git-16.266.66957-07591d7)
Kernel Version	4.4.19

I am happy to provide ANY additional information you required. I am an open source dev for Android and I TRULY APPRECIATE what you guys are doing here.
