Just updated the Odroid C2 to Kernel 4.10-rc4, but the Ethernet hang problem still persists..   Applied the dts Ethernet TX patch (see http://rglinuxtech.com/?p=1872 ) , and it works OK now..

There seems to be a bit of a backlog of Meson/GXBB patches, and I read that the Ethernet TX fix was supposed to be merged with -rc4, but there were objections to other patches in the bundle, and it has been pushed back – yet again!

It seems we may possibly have to wait for 4.11, to get full functionality on the C2?
