Use SHARC link ports in 48 bit mode for maximum transfer rates.


Use SHARC link ports in 48 bit mode for maximum transfer rates.
On series-3 cards, theoretical xfer for non-VHS=80Mby/s VHS=120Mby/s.
On series-4 cards, theoretical xfer for non-VHS=160Mby/s VHS=240Mby/s.
If specified transfer rate needs more resources than one side, it will
use resources from both sides requiring a MUXCLK=s flag.
This requires the host side buffer size to be a multiple of 6 bytes.

Series-5 cards do not have SHARC link ports.  The VHS flag is used to
place the hypertransport links in double rate mode.  Currently, the 
theoretical xfer rate per module for non-VHS=260Mby/s and VHS=520Mby/s.
Both modules must operate in the same mode and VHS is automatically 
applied if one of the modules may need it.  Use the VHS=0 flag to override this.
