Hello,

I don't have enough experience to answer all your question, but I'll try
to provide one suggestion:

configure.ac should contain:

AC_CHECK_HEADERS([net/ethernet.h sys/ethernet.h])

And in the header of your project:

#ifdef HAVE_NET_ETHERNET_H
# include <net/ethernet.h>
#else
# ifdef HAVE_SYS_ETHERNET_H
#  include <sys/ethernet.h>
# endif
#endif

If you need at least one of the headers, you can have this in configure.ac:

ethernet_h_found=no
AC_CHECK_HEADERS([net/ethernet.h sys/ethernet.h], [ethernet_h_found=yes])
if test $ethernet_h_found = no; then
        AC_MSG_ERROR([cannot find ethernet.h])
fi

Have a nice day,
