The quoted section is meant to explain in layman's terms that we are doing hardware offloading where possible. That means vectorized instructions for encryption and checksum-offloading and packet segmentation in the kernel / hardware driver where supported.
Being more efficient per packet means that we using less power to move the same amount of data, hence less power draw on mobile platforms.
Having said that, I agree that it could be better while still not be filled with technical jargon.
You should not write things with AI that you expect people to read
