2011-03-29cxgb3: Apply interrupt coalescing settings to all queuesAnton Blanchard1-4/+10
While testing the performance of different receive interrupt coalescing settings on a single stream TCP benchmark, I noticed two very different results. With rx-usecs=50, most of the time a connection would hit 8280 Mbps but once in a while it would hit 9330 Mbps. It turns out we are only applying the interrupt coalescing settings to the first queue and whenever the rx hash would direct us onto that queue we ran faster. With this patch applied and rx-usecs=50, I get 9330 Mbps consistently. Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S.

2011-03-28net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka5-7/+7
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem).

2011-03-28Net / jme: Do not use legacy PCI power managementRafael J. Wysocki1-14/+16
The jme driver uses the legacy PCI power management, so it has to do some PCI-specific things in its ->suspend() and ->resume() callbacks, which isn't necessary and should better be done by the PCI sybsystem-level power management code. It also doesn't use device wakeup flags correctly. Convert jme to the new PCI power management framework and make it let the PCI subsystem take care of all the PCI-specific aspects of device handling during system power transitions.

Avoid theoretical race condition regarding accessing dev->features NETIF_F_LRO flag, which is illustrated below.

2011-03-28can: c_can: Fix tx_bytes accountingJan Altenberg1-1/+1
The current SocketCAN implementation for the Bosch c_can cell doesn't account the TX bytes correctly, because it calls c_can_inval_msg_object() (which clears the msg ctrl register) before reading the DLC value: for (/* nix */; (priv->tx_next - priv->tx_echo) > 0; priv->tx_echo++) { msg_obj_no = get_tx_echo_msg_obj(priv); c_can_inval_msg_object(dev, 0, msg_obj_no); val = c_can_read_reg32(priv, &priv->regs->txrqst1); if (!(val & (1 << msg_obj_no))) { can_get_echo_skb(dev, msg_obj_no - C_CAN_MSG_OBJ_TX_FIRST); stats->tx_bytes += priv->read_reg(priv, &priv->regs->ifregs[0].msg_cntrl) & IF_MCONT_DLC_MASK; stats->tx_packets++; } } So, we will always read 0 for the DLC value and "ifconfig" will report *0* TX Bytes. The fix is quite easy: Just move c_can_inval_msg_object() to the end of the if() statement. So: * We only call c_can_inval_msg_object() if the message was actually transmitted * We read out the DLC value _before_ clearing the msg ctrl register Signed-off-by: Jan Altenberg <jan@linutronix.de> Acked-by: Kurt Van Dijck <kurt.van.dijck@eia.be> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.

2011-03-23ath9k: Fix TX queue stuck issue.Senthil Balasubramanian1-0/+2
commit 86271e460a66003dc1f4cbfd845adafb790b7587 introduced a regression that caused mac80211 queues in stopped state. ath_drain_all_txq is called in driver flush which would reset the stopped flag and the mac80211 queues were never started after that. iperf traffic is completely stalled due to this issue. Restart the mac80211 queues in driver flush only if the txqs were drained. Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-03-23ath9k: Fix kernel panic caused by invalid rate index access.Senthil Balasubramanian1-1/+1
With the recent tx status optimization in mac80211, we bail out as and and when invalid rate index is found. So the behavior of resetting rate idx to -1 and count to 0 has changed for the rate indexes that were not part of the driver's retry series. This has resulted in ath9k using incorrect rate table index which caused the system to panic. Ideally ath9k need to loop only for the indexes that were part of the retry series and so simply use hw->max_rates as the loop counter. Pasted the stack trace of the panic issue for reference.

On hardware busy the scan request pointer should be cleared, as higher levels will release. This avoids a crash when that pointer is erroneously used later. Signed-off-by: Joseph J. Gunn <armadefuego@yahoo.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
