From: Allan Stephens <allan.stephens@windriver.com>

Modify TIPC's broadcast link so that it counts each piece of a
fragmented message individually, rather than as treating the group
as a single message.  This ensures that proper correlation of sent
and received traffic can be done when the broadcast link statistics
are displayed, and is consistent with the way fragments are counted
by TIPC's unicast links.
