marius f63645c432 Fix a braino in r236469; the number of DMA tags required for handling
MAXPHYS should be based on PAGE_SIZE rather than SYM_CONF_DMA_BOUNDARY.
While at it, reuse the SYM_CONF_MAX_SG macro for specifying the maximum
number of DMA tags so sym(4) itself doesn't size memory beyond what's
required for handling MAXPHYS.

README.sym
----------
This file was bundled with the `sym' driver source files, when 
the driver was in development stage and not included yet into 
the FreeBSD repository. It described how to install the driver, 
gave informations on driver features and summerized important 
changes between versions. These informations are now available 
using `man sym' for driver usage and features description, and 
`cvs log' for driver changes.

I haven't removed this README file from the repository since 
I may have to provide additional documentation to people 
interested in understanding the driver sources and/or in helping 
driver development and maintenance.

As a result, this file is now under reconstruction. :-)
