Updated the Rock2 to Kernel 4.6-rc1:
......... Fedora 23 (Twenty Three) Kernel 4.6.0-rc1 on an armv7l (ttyS2) .................... # uname -a Linux rgrock2 4.6.0-rc1 #1 SMP Sun Mar 27 03:47:06 EDT 2016 armv7l armv7l armv7l GNU/Linux
The stmmac Ethernet driver bug from 4.5 Final has still not been fixed, and the driver code has changed in 4.6-rc1, and copying the 4.5-rc7 drivers no longer worked..
So.. I created patches from the diff between the 4.5-rc7 and 4.5 Final versions, and applied them to the 4.6-rc1 source..

The re-compiled, and re-booted, and Ethernet appears to work OK:
rk_gmac-dwmac ff290000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
But.. further tests show the link does not work..
