Does not build in Linux 4.4.0.. Tried tomerb and FS1360472174 fork also.

I'm getting the same error. Did you find a solution?

[kabo]

I managed to get by the first error by disabling IPv6 (Global build settings > uncheck "Enable IPv6 support in packages")

Next error seems to be because the signature for dst_output changed in linux 4.4 compared to 4.3.

Compare

http://elixir.free-electrons.com/linux/v4.3.6/source/include/net/dst.h#L494

to

http://elixir.free-electrons.com/linux/v4.4/source/include/net/dst.h#L490

Anyone have a patch for this change?
