Re: handing cloned frames to netif_rx()?
On Jan 11, 2008 3:17 AM, Johannes Berg [EMAIL PROTECTED] wrote: In 802.11n, there is a case where multiple data frames are received aggregated into a single frame (A-MSDU). Currently, we copy each of these frames out into their own skb, but because of the alignment with that etc. I started to think that we could simply pass up a clone of the original skb with start/length adjusted properly so that it windows only the contained packet. The buffer would be shared but the data within the original window (starting with the 802.3 header) could even be written to, it won't be needed again by mac80211 once it's handed off to netif_rx(). The skb will obviously have lots of head- and tailroom but that space would be part of other packets. Is it ok to do this? Will something freak out if we pass a cloned skb to netif_rx()? This would be great even in regular case. 4965 has ability to deliver more frames per receiving buffer Because of A-MSDU we keeps 8K receiving buffers which are underutilized when A-MSDU is not used. johannes -- 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

There are few traffic queues defined by the specs and the selection of the next queue to transmit a packet from, is determined in real time, just when there is a tx opportunity. This cannot be predicted in advance since it depends on the medium usage of other stations. WMM is a strict prio mechanism. The parametrization very much favors the high prio packets when the tx opportunity to send shows up. This is not true, there is no simple priority order from 1 to 4 , rather set of parameters that dermises access to medium. You have to emulate medium behavior to schedule packets in correct order. That's why this pushed to HW, otherwise nobody would invest money in this part of silicon :) Hence, to make it possible for wireless devices to use the qdisc mechanism properly, the HW queues should _ALL_ be non-empty at all times, whenever data is available in the upper layers. agreed. Or in other words, the upper layers should not block a specific queue because of the usage of any other queue. This is where we are going to disagree. There is no way the stack will send the driver packets which are low prio if there are some which are high prio. There is therefore, on contention between low and high prio, no way for low prio packets to obstruct the high prio packets; however, it is feasible that high prio packets will obstruct low prio packets (which is fine). cheers, jamal - 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 - 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
