This patch updates the fc_transport with statistics for local FC ports
(e.g. Hosts).  The statistics are defined per HBAAPI v2.0 definitions.

Caveats:
------------
- The information below is supplied by a simple test driver 
that does not
  talk to real hardware, but fully acts as a LLDD that supports the
  fc transport.


This patch results in the following in /sys/class:
