2009-08-28pktgen: use common idle routineStephen Hemminger
Simpler to have one place that spins and accounts for delays, this will also make the last packet be detected faster for more repeatable timing. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: spin using hrtimerStephen Hemminger
This changes how the pktgen thread spins/waits between packets if delay is configured. It uses a high res timer to wait for time to arrive. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: convert to use ktime_tStephen Hemminger
The kernel ktime_t is a nice generic infrastructure for mananging high resolution times, as is done in pktgen. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: avoid calling gettimeofdayStephen Hemminger
If not using delay then no need to update next_tx after each packet sent. This allows pktgen to send faster especially on systems with slower clock sources. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: reorganize transmit loopStephen Hemminger
Handle standard (and non-standard) return values in a switch. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: use netdev_alloc_skbStephen Hemminger
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>
2009-08-28pktgen: cleanup clone count testStephen Hemminger
The if statement to test for "should a new packet be used" can be simplified. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: xmit logic reorganizationStephen Hemminger
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. Miller <davem@davemloft.net>
2009-08-28pktgen: stop_device cleanupStephen Hemminger
All the callers were freeing skb after stopping device. Remove unneeded forward decl. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-28pktgen: change inliningStephen Hemminger
Don't force inlining where not needed. Gcc does better job of deciding to inline local functions. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28pktgen: minor cleanupStephen Hemminger
A couple of minor functions can be written more compactly. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-28qlge: Move TX completions from workqueue to NAPI.Ron Mercer
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>
2009-08-28qlge: Allow running MSIx with fewer vectors.Ron Mercer
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>
2009-08-28qlge: Get rid of 'default' rx_ring type.Ron Mercer
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.

2009-08-28bonding: Have bond_check_dev_link examine netif_runningPetri Gynther
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.

Random essid must be set to turn on radio when not connected. If device is in ad-hoc mode, this results 'media connect' indications with the random essid which should be ignored. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Increase scan delay from 1 sec to 6 sec. Spec says that scan by OID_802_11_BSSID_LIST_SCAN completes in 6 seconds.

2009-08-28b43: Implement antenna diversity support for LP-PHYGábor Stefanik
The A/G-PHY changes are fallout fixes from the enum change, which in turn allows the LP-PHY code to be much simpler.

2009-08-28b43: Enable LP-PHY support by default and remove Kconfig warningGábor Stefanik
The most common LP-PHY device, BCM4312, is now fully functional. So, no need to say "probably won't work for you" anymore. It's also not "for debuggers and developers only", as it is perfectly usable for end-users now (at least for BCM4312). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W.

2009-08-28ath5k: don't use PCI ID to find the chip revisionPavel Roskin
AR5K_SREV is available even if the chip has been put to sleep. Relying on the chip register allows binding non-standard PCI IDs by echo VENDOR_ID PRODUCT_ID >/sys/bus/pci/drivers/ath5k/new_id without having to specify the driver data as well.

2009-08-28ath5k: fix uninitialized value use in ath5k_eeprom_read_turbo_modes()Pavel Roskin
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.

2009-08-28ath5k: clarify srev comparison for CCMP checkBob Copeland
As Pavel Roskin noted, the check for mac version as copied from legacy_hal made no sense. This replaces it with the equivalent and makes up a suitable #define for the mac version legacy_hal checked.

2009-08-28iwlwifi: fix ICT irq table endiannessJohannes Berg
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 Stefanik
-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.

2009-08-28b43: LP-PHY: Fix and simplify Qdiv roundupGábor Stefanik
The Qdiv roundup routine is essentially a fixed-point division algorithm, using only integer math.
