Tested just the build not the function. By default it builds with the bundled liw. With the configure --enable-libnl3 it will build and link with the libnl3.

Currently:

• it links with the bundled liw even when the libnl3 is enabled, this shouldn't be problem the compiler optimizer should drop the unused objects
• it uses pkgconfig for the libnl3, but it doesn't check for it with the autotools macros
• it doesn't use auttools macros for checking of the libnl3 presence

you do intend to test it though, i presume ?

I had to readd the ethernet.h include, but now bellow the conditional, because otherwise it fails to compile with the libnl3.

I am not sure how to properly test it, I only run:

# ./reaver -i wlp3s0mon -b BSSID -vv

The AP indeed has WPS turned off, but it seems it's switching the channels.
