Detailed Description

Access the GAS through MRPC commands.

Access the gas through MRPC commands. The linux kernel may reject these commands if the process has insufficient permission.

MRPC commands respect the PAX ID where as standard gas access mechanisms may not.

These functions should generally not be used unless you really know what you are doing. The regular gas accessors (ie. gas_*()) will call these functions when switchtec_set_pax_id() has been used.
