One 'qed'? We have 2 distinct models - QED which provides core functionality
and supports several other modules as well [qedi, qedr and soon qedf], and
QEDE which contain the Ethernet networking logic.
It's true that there's a one-to-one mapping of instances [ each qede device
is connected to a single qed device], but there's a division of logic between
the two.
