net: Use conftest

Browse Source 
Instead of relying on kernel version to determine if functions or
specific versions of functions are present in the kernel, add compile
time tests to the conftest.sh script to determine this at compile time
for the kernel being used. This is beneficial for working with 3rd party
Linux kernels that may have back-ported upstream changes into their
kernel and so the kernel version checks do not work.
