2009-03-11tcp: allow timestamps even if SYN packet has tsval=0Eric Dumazet1-9/+0
Some systems send SYN packets with apparently wrong RFC1323 timestamp option values [timestamp tsval=0 tsecr=0]. It might be for security reasons (http://www.secuobs.com/plugs/25220.shtml ) Linux TCP stack ignores this option and sends back a SYN+ACK packet without timestamp option, thus many TCP flows cannot use timestamps and lose some benefit of RFC1323. Other operating systems seem to not care about initial tsval value, and let tcp flows to negotiate timestamp option. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: version bump to 64Ayaz Abdulla1-1/+1
This patch bumps up the version to 0.64 Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: fix irq clearing and napi spin lock changesAyaz Abdulla1-14/+4
This patch clears the irqstatus register with the exact same events it has read from it. Since the read-write operation is not atomic, a new irqstatus bit could have been set in between these operations and would then be cleared accidentally. Secondly, we now don't need any spin lock protection when scheduling/completing napi poll as the isr will not execute anymore (as we turn off all interrupts now). Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: performance changesAyaz Abdulla1-2/+2
This patch modifies the throughput mode poll settings to reduce the number of interrupts. This is only used by older hardware that need a timer irq in throughput mode. Secondly, this patch increases the default rx ring from 128 to 512. This drastically improves bandwidth utilization for small packets sizes i.e 512 bytes. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add interrupt moderation logicAyaz Abdulla1-31/+106
This patch adds the logic to moderate the interrupts by changing the mode between throughput and poll. If there has been a large amount of time without any burst of network load, the code will transition to pure throughput mode (where each tx/rx/other will cause an interrupt). If bursts of network load occurs, it will transition to poll based mode to help reduce cpu utilization (it will not interrupt on each packet) while maintaining the optimum network bandwidth utilization.

2009-03-10forcedeth: remove isr processing loopAyaz Abdulla1-147/+105
This patch is only a subset of changes so that it is easier to see the modifications. This patch removes the isr 'for' loop and shifts all the logic to account for new tab spacing. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add new optimization modeAyaz Abdulla1-48/+57
A new optimization mode called Dynamic has been added. This will be mode where interrupt moderation logic will dynamically switch between pure throughput mode and poll based (called 'cpu') mode. Also, for newer chipsets, the timer irq is not needed for throughput mode. Secondly, since we are modifying the irqmask to change between modes, msix is not supported.

2009-03-10forcedeth: napi - handle all processingAyaz Abdulla1-38/+60
The napi poll routine has been modified to handle all interrupt events and process them accordingly. Therefore, the ISR will now only schedule the napi poll and disable all interrupts instead of just disabling rx interrupt. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: add/modify tx done with limitAyaz Abdulla1-6/+14
There are two tx_done routines to handle tx completion processing. Both these functions now take in a limit value and return the amount of tx completions. This will be used by a future patch to determine the total amount of work done. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: remove overheadAyaz Abdulla1-32/+4
This patch removes unnecessary overhead code. Firstly, there is no nead to mask off unwanted interrupts as we will be checking against the irqmask field anyways. Secondly, there has been no value in last few years from detecting error or unknown interrupts. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: save irq events for napi processingAyaz Abdulla1-24/+23
This patch will save the irq events in the driver's context so that the napi routine knows which interrupts have occurred. Subsequent changes will be moving all interrupt processing into the napi poll routine. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-10forcedeth: remove msix + napiAyaz Abdulla1-21/+5
This patch removes support for msix running in conjunction with napi. There has been reported issues regarding the behaviour of irqmask and generation of interrupts by the HW when in MSIX mode. When running napi, the driver is constantly turning off/on the irqmask. For the time being, I am going to disable it until I can root cause the issue.

2009-03-10forcedeth: fix stats version featureAyaz Abdulla1-6/+6
Newer versions of the stats feature would not encompass all older versions. This would result in only retreiving a subset of all available stats in HW. Signed-off-by: Ayaz Abdulla <aabdulla@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

A number of functions in the usb_gigaset module will return -EINVAL if CONFIG_GIGASET_UNDOCREQ is not set. Make these return -ENOTTY as it's more specific and it might make it easier to see (from userspace) why these functions actually fail.

2009-03-05ath9k: Add a debugfs interface for controlling virtual wiphysJouni Malinen2-0/+165
debugfs ath9k/phy#/wiphy can be used to show the current list of virtual wiphys and to add/remove virtual wiphys. Eventually, this interface could be replaced with a cfg80211/nl80211 command that is passed through mac80211. For example: # cat /debug/ath9k/phy0/wiphy primary: phy0 # echo add > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 secondary: phy1 # echo del=phy1 > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 In addition, following commands can be used to test pausing and unpausing of the virtual wiphys: pause=phy1 unpause=phy1 select=phy1 (select pauses and unpauses wiphys automatically based on channel) schedule=500 (set wiphy scheduling interval in msec; 0 = disable; default value: 500) Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-03-05ath9k: Add a simple virtual wiphy schedulerJouni Malinen3-0/+72
This is a very simple scheduler that goes through the wiphys and schedules one at a time every N milliseconds (current default value: 500 ms). This is enough for initial testing, but there are number of areas where a more complex scheduler can improve operations greatly.

2009-03-05ath9k: Special processing for channel changes during scanJouni Malinen3-10/+68
Allow mac80211-controlled channel changes on an active wiphy and especially during a scan. We need this as long as the scan is controlled by mac80211. Moving this control into the driver could allow some optimizations on scanning while using multiple virtual interfaces, but for now, try to work as well as possible with the current scan mechanism.

2009-03-05ath9k: Add workaround to recover from failed channel changesJouni Malinen3-2/+43
It looks like channel change may fail in some cases and end up leaving the hardware in state where it cannot transmit any frames. Add a workaround to recover from this state if we detect that wiphy selection is failing due to wiphys not leaving PAUSING state.
