-* qla2x00_proc_info
-*
-* Description:
-*   Return information to handle /proc support for the driver.
-*
-* inout : decides the direction of the dataflow and the meaning of the
-*         variables
-* buffer: If inout==0 data is being written to it else read from it
-*         (ptr to a page buffer)
-* *start: If inout==0 start of the valid data in the buffer
-* offset: If inout==0 starting offset from the beginning of all
-*         possible data to return.
-* length: If inout==0 max number of bytes to be written into the buffer
-*         else number of bytes in "buffer"
-* Returns:
-*         < 0:  error. errno value.
-*         >= 0: sizeof data returned.
