[LTP] [PATCH v1] lib/tst_test.sh: skip test if ip returns "Error: Unknown device type"

[Petr Vorel <pvorel@suse.cz>]

Hi Radoslav,

> In network stress test groups there are tests expecting
> CONFIG_NET_IPVTI to be enabled in the kernel, and if it's not they
> fail. There is a check for VTI support in the ip utility, but not
> for the kernel. Skip these tests if vti device type is not known by
> the kernel.

LGTM.
