The IEEE Std 802.1Q specs for credit-based shaper require precise transmit decisions
within a 125 microsecond window of time.
Even with the Preempt RT patch or similar enhancements, that isn't very practical
as software-only. I doubt that software would conform to the standard's
requirements.
This is analogous to memory, or CPU.
I feel like this is looking for an excuse to not have to at least try to implement
the software version of CBS.
