Is there anything else I should do to confirm whether or not this is an upstream issue?

OS: Ubuntu 16.04.1 LTS Server Edition - upgraded from 12.04 LTS By default Ubuntu chooses the r8169 module for this controller, which does not work correctly. (This has been an issue for a number of releases). Realtek provide a Linux driver at the below site: http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false With previous Ubuntu releases, compiling and using this module has worked perfectly, however with Ubuntu 16.04.1 I have had limited success. I have downloaded and compiled v1.030 and used it with a number of supported kernels but am getting similar issues with all. Note that I have also disabled IPv6 on this machine having seen indications that this may be causing the problem - I have seen no change in behaviour since doing this. Kernel 4.4.0-34-generic > Immediately following boot (or depmod r8101) the interface works and I can successfully communicate over the interface I have seen consistent downloads of 6MB/s. At a seemingly random point later, connectivity will cease without warning. At this time the stats (RX/TX bytes/packets) in ifconfig cease to increase but the interface remains UP. A ping to the locally configured static IP returns successfully. "ifdown && ifup" does not fix the problem, but "rmmod && depmod" does. The point at which the connectivity ceases does not appear to be consistent in either time or amount of data transferred. Will append further debugging information when I can get it off the server.
