The TX work is so incredibly cheap, relatively speaking, compared to the full input packet processing path that the RX side runs that I see no real benefit. In fact, you might even get better locality due to the way the locking can be performed if TX reclaim runs inside of ->poll() - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
