Hi,
this appears to be only half of the fix.

now rp->ai_socktype will be SOCK_DGRAM and rp->ai_protocol UDP. So the
'raw'
socket for GRE will be a datagram socket for UDP.
E.g. you need the second hunk from my workaround[1]. I just wondered if you
could think about a better way (one that can be easily dumped or ifdefed
without putting the special case in the middle).
