I was running 2.6.25 plus the patch from here:
    http://marc.info/?l=linux-netdev&m=120905226611742&q=raw

But I tried getting 2.6.26 and I have the same problem:

[root at C100273 iproute2-2.6.26]# ip/ip link set eth4 netns 24755
RTNETLINK answers: Invalid argument

I'm pretty certain I'm running the right "version" of the command.  It
does install it to /usr/sbin/ip, but if I run the version that came with the
distribution (in /sbin/ip), I get a different error reporting netns as garbage.
So.. since it at least parses the netns argument and sends the netlink request,
it at least seems to be making it to the kernel.

Does the kernel.org version of 2.6.29-rc1 have everything I need?

Any other ideas?

Thanks,
Chris
