As Ben Hutchings pointed out, hw_features is still setting this...but
I'm not sure how that matters.
ax88179_set_features() doesn't allow setting SG or TSO features. But
I expect it would be "not too difficult" to add such that ethtool
could set those features after boot. Or perhaps add a driver module
parameter to set these features. I just guessing the skb_linearize()
could be removed until set_features support for SG and/or TSO is
added. Is that correct?
thanks,
grant
