Hi!
A discussion recently took place on the power mailing list on the
subject of the impact of (hardware-assisted) offload functions* on the
power efficiency of the overall system.
The discussion was brought on by me noticing that not all drivers enable
all of their offload features by default (case in point: r8169).
Although the discussion may not be complete, early indications are that:
1. Hardware-assisted offloads improve power efficiency unless
implemented in a separate CPU (TOE / Total Offloading);
2. It would probably be a good idea to enable hardware-assisted offloads
other than TOE by default given the above.
I would therefore like to sollicit views here:
1. Would changing default offload settings in Ethernet drivers help to
save the planet?
2. Which offload settings does it make sense to enable by default?
*: see ethtool -k ethX for what I'm talking about, knowing that 'generic
segmentation offload' is not hardware-assisted.
Thanks, Jan
