2009-08-07net: Avoid enqueuing skb for default qdiscsKrishna Kumar4-51/+108
dev_queue_xmit enqueue's a skb and calls qdisc_run which dequeue's the skb and xmits it. In most cases, the skb that is enqueue'd is the same one that is dequeue'd (unless the queue gets stopped or multiple cpu's write to the same queue and ends in a race with qdisc_run). For default qdiscs, we can remove the redundant enqueue/dequeue and simply xmit the skb since the default qdisc is work-conserving. The patch uses a new flag - TCQ_F_CAN_BYPASS to identify the default fast queue. The controversial part of the patch is incrementing qlen when a skb is requeued - this is to avoid checks like the second line below: + } else if ((q->flags & TCQ_F_CAN_BYPASS) && !qdisc_qlen(q) && >> !q->gso_skb && + !test_and_set_bit(__QDISC_STATE_RUNNING, &q->state)) { Results of a 2 hour testing for multiple netperf sessions (1, 2, 4, 8, 12 sessions on a 4 cpu system-X).

2009-08-06vxge: fix pktgen hangs (don't abuse skb->cb[])Benjamin LaHaise5-32/+40
This patch fixes a case in the transmit completion code which was resulting in pktgen hanging at the end of a run. The cause is due to the fact that the ->cb[] area of an skb cannot be used in a network driver's transmit path, as that area belongs to the network protocol. Pktgen hangs, as it sends out the same packet multiple times, and vxge's use of this area of the skb for a temporary list can only add the packet to the temporary list once (while it may be on the queue many times). The fix is to remove this abuse of skb->cb[]. Instead, skb pointers are placed into a temporary stack array, and then free outside of the tx lock. This retains the smp optimization of doing dev_kfree_skb() outside of the tx lock.

2009-08-06ixgbe: allow vlan egress priority mapping in DCB modeLucy Liu1-1/+1
The skb priority to vlan-qos egress mapping that can be configured using set_egress_map with vconfig is overriden by the DCB code in the driver. This patch allows this existing mechanism to work and will increase the configuration flexibility of DCB mode on Linux. A hierarchy of configuration is: 1. Modifies the ixgbe_select_queue() routine for DCB mode to return the priority value from the VLAN tag. It will normally be zero, unless the egress priority map has modified it. This will get packets into the correct queue and result in the queue_mapping field being set correctly. 2. Any tc filter which modifies queue_mapping will be honored, as the filters are handled after the vlan egress map is handled.

2009-08-05mac80211: FIF_PSPOLL filter flagIgor Perminov4-5/+26
When an interface is configured in the AP mode, the mac80211 implementation doesn't inform the driver to receive PS Poll frames. It leads to inability to communicate with power-saving stations reliably. The FIF_CONTROL flag isn't passed by mac80211 to ieee80211_ops.configure_filter when an interface is in the AP mode. And it's ok, because we don't want to receive ACK frames and other control ones, but only PS Poll ones. This patch introduces the FIF_PSPOLL filter flag in addition to FIF_CONTROL, which means for the driver "pass PS Poll frames". This flag is passed to the driver: A) When an interface is configured in the AP mode. B) In all cases, when the FIF_CONTROL flag was passed earlier (in addition to it).
