The VP-1025 is similar to the other cards supported by the dst module, 
except that there are 2 versions of this card having different firmware 
versions and the later version of the card had some difficulty in 
getting "found" by the module.

Please do check whether you see any differences in the behaviour with 
the updated tree. Other than that, what you do looks mostly okay to me. 
(FEC should not be a problem)
