description:
Add support for the Oxford Semiconductor OXPCIe952, a 2-port serial chip
with a PCI Express interface, in legacy mode.  Cursorily tested with a
StarTech PEX2S952LP.

See the manual for your adapter to see how to put it into legacy mode.
There is also a "native" mode that uses a different clock multiplier
and (I think) provides a richer feature set, but also requires a bit of
additional initialization (see FreeBSD's puc(4)).

The native-mode PCI functions use different PCI Device IDs than the
legacy-mode functions.
