This is a good long-term plan, but right now we have to do something reasonable. A quick scan shows that smsc75xx, smsc95xx, and ax88179_178a all have this problem. Instead of the patch starting this thread, I'd like to see one that hits all three drivers and removes all SG and TSO features bits from both the ->features _and_ ->hw_features settings. Could someone toss that together quickly?
