Network problems with sendto() syscall

[Bruce M. Simpson]

I strongly suspect this is related to an introduced bug in the 
RTM_CHANGE path.

Please run 'route -nv monitor' in its own shell and monitor its output 
while you run bootpd.

If the problem happens after RTM_CHANGE then it is probably the bug that 
cognet found, it has a very simple fix which just needs to be committed 
ie above line 531 in rtsock.c:
      if ((rt->rt_flags & RTF_LLINFO) == 0)
