Hi Eric,

Can you please tell us if this change would be for the better?

I was about to say yes to this request but checked and no other Ethernet driver seems to use the queue trans_start.
I was able to find your patch "net: tx scalability works : trans_start" [ http://patchwork.ozlabs.org/patch/27104/ ] but did not find more about this topic.
 

Drivers no longer have to worry about updating trans_start themselves.
Core networking stack handles this.

Check txq_trans_update() done from netdev_start_xmit()
