Hello!
As reported in http://bugs.debian.org/575970 there is currently a warning
printed for every tunnel when using latest iproute2 on atleast <= 2.6.32
kernels (missing 6rd?!).
The attached patch avoids perror when errno is EINVAL, which I assume
is the way to detect missing 6rd support. A better/cleaner
method to detect and avoid 6rd when there's no kernel support
is more then welcome.

I will wait (a little while) to see if Alexandre has a preferred alternative.
IMHO, the proper way to detect 6rd kernel missing support is to catch
EINVAL, but not others errno since they might be usefull in some case.
Reading the code again, there is also a need to test tunnel protocol since
6rd scope is ipv6/ip only.
I will send another email with a proposed patch to fix those 2 issues.
Regs,
Alexandre
