[LTP] [PATCH 2/2] testcases: netns: Handle "Operation not supported" error

[Petr Vorel <pvorel@suse.cz>]

Hi Mylène,

> If there is no support for "dummy" or "veth", the tests will fail

>    RTNETLINK answers: Operation not supported
>    netns_sysfs 1 TBROK: failed to add a new (host) dummy device
> and
>    RTNETLINK answers: Operation not supported
>    netns_comm_ip_ipv6_ioctl 1 TBROK: unable to create veth pair devices
>    Cannot find device "veth0"

> This commit is storing the output of the commands and verifies
> if there is any reference to "Operation not supported".
> This code is based on what it is already done in "ipsec_lib.sh"
> stress test.
