The MAD agent is created to handle sending MADs that the device itself
generates -- traps and notices essentially. Look at
mthca_mad.c::forward_trap() to see where it gets used.
MADs from the network are passed down to the firmware in the
process_mad method, and those replies are returned back up the the MAD
layer for sending.
