Hi Richard,

Sure, that would be great.

I can not really tell if they are similar; I don't have the datasheet
for the 6350/6351. The datasheet for the 6352 covers a couple of other
switches, but not those two. The 6352 does support PTP; I can see that
much in its datasheet. You could check if my 6352 driver works for you ;-).

Thanks,
