API incompatible with HWE edge

[Kai Gillmann]

This is on a Intel Compute Stick STK1AW32SC (Atom x5-Z830) using elementaryos-0.4.1-20170814 (Xenial 16.04 LTS) and bcmwl-kernel-source 6.30.223.271+bdcom-0ubuntu1~1.1

The default kernel does not provice all required drivers to operate all hardware. Currently installed is HWE.

This problem happens when installing HWE-edge.

The problem is:
/var/lib/dkms/bcmwl/6.30.223.271+bdcom/build/src/wl/sys/wl_linux.c:2922:10: error: ‘struct net_device’ has no member named ‘last_rx’

As far as I read online, last_rx was removed / moved. So the driver source seems incompatible with newer kernel versions.

Expected behaviour:
Installing HWE should include all required dependencies (like it does with Xorg) so that at least the recent LTS version can be fully functional on hardware that requires a more modern kernel than the default one.
