I thought the correct use is to get this lock on clean_tx side which can get called on a different cpu on rx (which also cleans up slots for skbs that have finished xmit). Both TX and clean_tx uses the same tx_ring's head/tail ptrs and should be exclusive. But I don't find clean tx using this lock in the code, so I am confused :-) - KK - 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
