Some of this seems to be taken from the gelic driver, so shouldn't
the copyright info from there be included here?

Moreover, if there is a significant amount of code duplication
between this driver and gelic, I would expect to actually share
the code instead, either by integrating the udbg code into the
gelic driver in form of netconsole support, or by moving the
common parts into a separate module.

No, thankfully there is no significant code duplication :)
It contains a few structs and defines found elsewhere, but that's
because it's not a real netdev. It just prepares the eth/ip/udp header
once for its single purpose, then uses the hypervisor to send and poll
- in contrast to the gelic driver, which reuses its irqhandler for
netconsole support.
