* 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.
