Some years ago, I did a consulting job for Emulex to implement software
density selection in the ts driver for a *modified* TC13 (they had a
customer who wanted it).  It worked, but did require special ROMs in
the TC13.  There was some problem with version mismatch when I sent
them the driver initially - it didn't test correctly on the hardware
they had in house, although it did work on my development system.
After an hour or so of demonstrating the problem at their facility, the
problem turned out to be with the particular transport they had - it
worked correctly with the Cipher I used for debugging.  Beyond that, I
don't remember the details of the problem.

Since that time, Emulex has been massively reorganized, and I've found
them *very* unresponsive to Unix-related problems.
