2009-08-29pktgen: use netdev_alloc_skbStephen Hemminger1-4/+6
netdev_alloc_skb is NUMA node aware. Also, don't exhaust atomic emergency pool. Don't want pktgen to cause OOM behaviour. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-29pktgen: xmit logic reorganizationStephen Hemminger1-31/+24
Do some reorganization of transmit logic path: * move transmit queue full idle to separate routine * add a cpu_relax() * eliminate some of the uneeded goto's * if queue is still stopped, go back to main thread loop. * don't give up transmitting if quantum is exhausted (be greedy) Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2009-08-29qlge: Move TX completions from workqueue to NAPI.Ron Mercer2-136/+137
TX completions were running in a workqueue queued by the ISR. This patch moves the processing of TX completions to an existing RSS NAPI context. Now each irq vector runs NAPI for one RSS ring and one or more TX completion rings. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-29qlge: Allow running MSIx with fewer vectors.Ron Mercer1-47/+38
Currently we downshift to MSI/Legacy if we don't get enough vectors for cpu_count RSS rings plus cpu_count TX completion rings. This patch allows running MSIX with the vector count that the platform provides. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-29qlge: Get rid of 'default' rx_ring type.Ron Mercer4-64/+28
Currently we have three types of RX rings. 1) Default ring - services rx_ring for broadcast/multicast, handles firmware events, and errors. 2) TX completion ring - handles only outbound completions. 3) RSS ring - handles only inbound completions. This patch gets rid of the default ring type and moves it's functionality into the first RSS ring. This makes better use of MSIX vectors since they are a limited resource on some platforms.

2009-08-29bonding: Have bond_check_dev_link examine netif_runningPetri Gynther1-0/+3
bonding: Have bond_check_dev_link examine netif_running Some network devices do not call netif_carrier_off when they are set administratively down. Have the bonding link check function also inspect the netif_running state. Ignore netif_running if the bond_check_dev_link function is called with "reporting" set, as in that case it's inspecting the capabilities of the non-netif_carrier device driver.

2009-08-28ath5k: fix uninitialized value use in ath5k_eeprom_read_turbo_modes()Pavel Roskin1-24/+5
The `val' variable in ath5k_eeprom_read_turbo_modes() is used uninitialized. gcc 4.4.1 with -fno-inline-functions-called-once reports it: eeprom.c: In function 'ath5k_eeprom_read_turbo_modes': eeprom.c:441: warning: 'val' may be used uninitialized in this function Comparing the code to the Atheros HAL, it's clear that the split between ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was incorrect. The Atheros HAL reads both turbo and non-turbo data from EEPROM in one function. Some turbo mode parameters are derived from the same EEPROM values as non-turbo parameters, just from different bits. Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to fix the warning. The actual values and offsets have been cross-checked against Atheros HAL.

2009-08-28iwlwifi: fix ICT irq table endiannessJohannes Berg2-6/+6
The ICT IRQ table is a set of __le32 values, not u32 values, so when reading it we need to take into account that it has to be converted to CPU endianness. This was causing a lot of trouble on my powerpc box where various things would simply not work for no apparent reason with 5xxx cards, but worked with 4965 -- which doesn't use the ICT table.

2009-08-28b43: Fix and update LP-PHY codeGábor Stefanik5-81/+122
-Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*) in the channel tune routines. -Fix some typos & spec errors found by MMIO tracing. -Optimize b43_phy_write & b43_phy_mask/set/maskset to use only the minimal number of MMIO accesses. (Write is possible using a single 32-bit MMIO write, while set/mask/maskset can be done in 3 16-bit MMIOs). -Set the default channel back to 1, as the bug forcing us to use channel 7 is now fixed. With this, the device comes up, scans, associates, transmits, receives, monitors and injects on all channels - in other words, it's fully functional. Sensitivity and TX power are still sub-optimal, due to the lack of calibration (that's next on my list). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W.
