Hi guys - I can confirm 4.5.0 minus 88f8b1b works for me:
root at lime2-079f:~# cat /proc/version
Linux version 4.5.0-minus-88f8b1b (root at lime2-079f) (gcc version 4.9.1
(Ubuntu/Linaro 4.9.1-16ubuntu6) ) #2 SMP Wed Mar 16 12:50:03 UTC 2016
From dmesg output:
[ 9.731730] NET: Registered protocol family 10
[ 10.516893] RX IPC Checksum Offload disabled
[ 10.516948] No MAC Management Counters available
[ 10.517374] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 15.505548] sun7i-dwmac 1c50000.ethernet eth0: Link is Up -
1Gbps/Full - flow control off
[ 15.505660] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
.. and connected over ethernet.
Thanks, best,
-bert
