 Hi
 
 dhcpcd currently uses this macro like so
 
 /*
   * BSD kernels don't inform userland of DAD results.
   * See the discussion here:
   *    http://mail-index.netbsd.org/tech-net/2013/03/15/msg004019.html
   */
 #ifndef __linux__
 /* We guard here to avoid breaking a compile on linux ppc-64 headers */
 #  include <sys/param.h>
 #endif
 #ifdef BSD
 #  define IPV6_POLLADDRFLAG
 #endif
 
 /* This was fixed in NetBSD */
 #ifdef __NetBSD_Prereq__
 #  if __NetBSD_Prereq__(6, 99, 20)
 #    undef IPV6_POLLADDRFLAG
 #  endif
 #endif
 
 Should this be now be moved to a ./configure test based on uname -m?
 ./configure is NOT run when dhcpcd is imported into external so that may
 complicate future pullups if changed.
