i.e. sending the drive-to-drive control word and reference 1 to
a certain drive or group of drives. The message can then be
further relayed to another group of drives to form a multicast
chain.

followers relaying the message to other followers), the
sources for the control word and reference 1 are selected by
parameters
57.08 Follower cw src and 57.06 Ref 1 src
