The first patch here fixes two bugs on ppc32, and mips32.  It fixes one
bug on arc and arm32 (in certain configurations).  It probably makes
sense to get it in ASAP through the networking tree.  I'd like to see
testing on those four architectures if possible?

Sorry I don't have easy access to any hardware that fits the bill. At
some point I'll be able to go to the office and setup a machine that (I
think) can test these paths, but I don't have an ETA on that.

You and others seem to have done lots of analysis on this though, so I
think you should merge the fixes without waiting on ppc32 testing.

cheers

The second patch enables new functionality.  It is much less urgent.
I'd really like to see Mel & Michal's thoughts on it.

I have only compile-tested these patches.
