It looks little awkward, but should be enough for people who care about
defaults from kernel.
Fix#26
Also fixed bug with setting TxQLen for main device. It was never set
before.

Creating a link in one namespace and then moving can
be problematic since there could be a iface name conflict.
However, it is not always possible to switch into the target
namespace either -- e.g. creating a macvlan interface must
be done in the namespace of the parent interface.
