Alexander Motin 6514cb18d9 pms(4): Limit maximum I/O size to 256KB instead of 1MB. 
There is a weird limit of AGTIAPI_MAX_DMA_SEGS (128) S/G segments per
I/O since the initial driver import.  I don't know why it was added,
can only guess some hardware limitation, but in worst case it means
maximum I/O size of 508KB.  Respect it to be safe, rounding to 256KB.

3. Process To Rebuild the Driver Module
---------------------------------------
  1. from the directory freebsd/ini/src, type "make clean".

4. Loading and Unloading Driver Module
--------------------------------------
  Type "kldload ./pmspcv.ko" to load the driver 

  Type "kldunload pmspcv.ko" to unload the driver

5. Description
--------------
  1. This driver has been built and tested on FreeBSD 9.0 amd64


6. Additional Notes
-------------------------------------
 1. This section covers how phy ID in PhyParms should be used in the
    different types of the controller. In SPCv/SPCve controller (8-phy
    controller),
    PhyParms[0-3] are mapped to Phy0-3 and PhyParms[8-11] are mapped to Phy4-8. 
    In SPCv+/SPCve+ controller(16-phy controller), PhyParms[0-15] are mapped to
    Phy 0-15.
