Comment (by Gedare Bloom):

 Probably the 'buf' should be aligned to the structure alignment since it
 gets cast to HEADER struct. You can at least use CPU_STRUCTURE_ALIGNMENT
 macro, or else create a union, something like this might work

 {{{
 union {
   struct {
     HEADER header;
     u_char payload[RTEMS_ZERO_LENGTH_ARRAY];
   };
   u_char buffer[MAXPACKET];
 } x;
   u_char *buf = x.buffer;
 }}}
