+| Compute bandwidth

+| | ... | Compute (bidir) bandwidth from given (unidir) transaction rate.

+| | ... | This keyword reads "ppta" and "avg_frame_size" set elsewhere.
+| | ... | The implementation should work for both pps and cps rates.

+| | ... | *Arguments:*
+| | ... | - tps - Transaction rate (unidirectional) [tps]. Type: float
+| | ...
+| | ... | *Returns:*
+| | ... | - Computed bandwidth in Gbps.
+| | ... | - Computed aggregate packet rate in pps.
