/* Back in NET2 (and before?) the ifreq.ifr_hwaddr was a char array,
   but in NET3 it is now a "sockaddr", and we need the data part.

   The code to work on older kernels has now been removed as it caused
   problems on some systems where this test no longer works (e.g. the
   AlphaLinux).  Is anyone really running 1.1.13 or earlier kernels
   anymore?

   If you still have an old kernel and need bootpc stick with version
   0.45 which is the last release to support the NET2 code.
