Re: Iproute2 build broken by current kernel headers

These patches will have to be redone to work with the revised include
files. The iproute2 changes are not acceptable as is because they do not support
older kernels.

It is critical that the resulting code work on both old and new
kernels. In other words, when the new ss command is built (using your
patches and 3.3 headers), it:
 * SHOULD send new diag requests to kernel and be able to display
   the new UNIX domain info
 * MUST still work when run against old 3.2 kernel.

This means the code should send new request first, and if that generates
an error fallback (silently) to the old message format.

OK, I will rework the patches in this way.

Thanks,
Pavel
