Yep, I thought about it, but it might get tricky to handle it:
tcp needs two, one for listening sockets and one for connected ones.

We don't need to worry about the listening socket for this patchset,
should we then just keep that in the tcp struct, and use the tag as
the generic one in CharDriverState for all of the backends?
