So far we were sending link data as a string. It got some drawbacks:
1) Didn't allow writing clean user space apps reading link state. It was
needed to do some screen scraping.
2) Forced whole PORT_LINK communication to be string based. Adding
support for *setting* port link required passing string and parting
it in the kernel space.
