I've read IPv4 gre code, and it appears to do the right thing on rx, but it
does *not* appear to handle namespaces correctly on transmit. In general,
I would expect pretty much all code to get namespace handling correct for
the rx case. I'll have a closer look at fixing this tomorrow if nobody else
beats me to it.
