I was just defining the well known methods.  I can remove this.

The kernel module exports two files to perform operations on: ib_usa_raw and 
ib_usa_default.  An administrator can control access to these files however they 
like.  Operations performed through ib_usa_default are limited to specific SA 
queries.  Sends performed through ib_usa_raw are not filtered in the kernel, so 
behave more like sending requests through the userspace MAD interfaces.
