I have applied this to my Rock2 - Kernel 4.6-rc1 - and eth0 is present,
now, but no network traffic gets through:

To rock2:
$ ping rgrock2
PING rgrock2 (192.168.0.xx) 56(84) bytes of data.
^C
--- rgrock2 ping statistics ---
9 packets transmitted, 0 received, 100% packet loss, time 7999ms

>>From rock2:
# ping 192.168.0.x
PING 192.168.0.x (192.168.0.2) 56(84) bytes of data.
>>From 192.168.0.xx icmp_seq=1 Destination Host Unreachable

--- 192.168.0.x ping statistics ---
9 packets transmitted, 0 received, +8 errors, 100% packet loss, time 8001ms

Everything worked OK with kernel 4.5-rc7, and with 4.5 Final with the
-rc7 versions of stmmac_platform.c and stmmac_mdio.c substituted..
