Cubox-i ethernet broken on 4.18.x Kernels

[Siavash Safi]

Hello,

I mentioned this issue on IRC but also posting here:
I've been using Fedora on Cubox-i for a long time, I noticed that 4.18.x kernels broke networking. Booting to 4.17.19-200.fc28 fixes the issue for me.
The eth0 interface is still visible on 4.18.x kernels but it does not work:
- The interface was connected to an Amplifi HD, the link kept going up/down every few seconds (no such issue on older kernels)
- Connecting the interface to a Cisco switch fixes the unstable link issue, the rest of the tests were done with this switch
- DHCP hangs (tested manually with dhclient, no output)
- Setting an static IP on the interface works but no traffic passes through (tested ICMP, etc.)
I can provide more technical details and kernel log messages if required.

Thanks,
Siavash
