* net,pppoe: fixup module init/exit subsequent callsCyrill Gorcunov2009-08-12
| | | | | | | | | pernet data should allocated first and freed last on module init/exit routines otherwise it's possible to have unserialized calls to packet handling routines. Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Avoid enqueuing skb for default qdiscsKrishna Kumar2009-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* mlx4_en: Not using Shared Receive QueuesYevgeny Petrilin2009-08-06

| * mac80211: FIF_PSPOLL filter flagIgor Perminov2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If hw initialization fails (ath9k_hw_init()) on ath_init_softc() we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach() is conditional though as ath9k_hw_init() could itself have called ath9k_hw_detach(). Just describing this is itself a brain twister.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Unloading rt61pci can leave the device in such state that reloading rt61pci would fail to reinitialize it. Bogus data would be read from the EEPROM and the RF version won't be recognized. It appears that unloading rt61pci with power saving enabled would have such effect. To initialize the device properly, SOFT_RESET_CSR should be set to the same value as rt61pci_config_ps() uses to wake up the device.
