1. An apparatus comprising circuitry configured to:
receive a first plurality of frames of a first interface group at a first rate,
determine idle/stuffing data to be added in each of the first plurality of frames based on a second rate associated with a second plurality of frames of a second interface group,
add information about the idle/stuffing data in each frame of the first plurality of frames in a preceding frame for recovery by a receiver, wherein the second plurality of frames each include a variable frame length, and
transmit the second plurality of frames of the second interface group with the idle/stuffing data included therein, wherein the second plurality of frames includes the first plurality of frames with the idle/stuffing data.
