Stephen,

Thanks for your reply. My experience with the r8169 driver is that it 
does support rx checksumming, tx checksumming, scatter/gather and tcp 
segmentation, but out of the above only enables rx checksumming by default.

The other two ethernet drivers I have hardware for don't support any 
hardware-assisted offloads (that is: they all support generic 
segmentation offload but that isn't hardware-assisted and it is also not 
enabled by default).

Best regards, Jan
