Specifically, handle ampdu_action and attempt to start a BA session on receiving the first qos packet from mac80211 for transmission to a HT sta. While the BA session is being created, all the packets belonging to that stream will be dropped to prevent sequence number mismatch at the recipient.

We now have two different kinds of queues. And the number of AMPDU queues may vary. So we must be clear about which queues we are dealing with. Note that when we report the number of queues to mac80211, we only report the WMM queues. Based on work by Yogesh Powar <yogeshp@marvell.com>.

Firmware APIv2 adds the following enhancements: -- capabilities are reported by the firmware -- API supports up to 8 dedicated AMPDU streams -- optional packet timestamping and expiration can be enabled. Specifically, packets that are queued in firmware for longer than 500ms will be dropped if this option is used.

Specifically, APIv2 will specify a variable number of AMPDU queues in the MWL8K_CMD_GET_HW_SPEC. So init the tx queues after MWL8K_CMD_GET_HW_SPEC for ap fw. Also, we make it safe to deinit queues that have not been init'd. This happens if the mwl8k_get_hw_spec_ap routine fails, for example.

Fine-tuning register write operation and avoid unnecessay delays for ath9k_htc driver, saves hw reset time which improves scanning time and also solves one of the following scenario. Sometimes the ACK is sent by STA for assoc response is not seen at AP side. So the AP continues to send retry assoc responses. At the STA side, since the assoc response was already forwarded to mac80211, it proceeded to channel change which in turns does chip reset. In most of the cases the chip reset was completed before max retries are reached at AP side. Hence STA can able to ACK the retried frames again. But in clear environment these retries are completed within shortspan of time. Since ath9k_htc consumes more time for hw reset, this latency is causing dissociation by AP due to max reties are reached. This issue was originally reported with Cisco Aironet 1250 AP in HT40 mode in noise free environment. Signed-off-by: NRajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: NJohn W.

This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

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: NAnton Blanchard <anton@samba.org> Acked-by: NDivy Le Ray <divy@chelsio.com> Signed-off-by: NDavid S.

In commit 95a0f10c ("drbd: store in-core bitmap little endian, regardless of architecture") drbd had made the sane choice to use little-endian bitmap functions everywhere. However, it used the horrible old functions names from <asm-generic/bitops/le.h>, that were never really meant to be exported. In the meantime, things got cleaned up, and in commit c4945b9e ("asm-generic: rename generic little-endian bitops functions") we renamed the LE bitops to something sane, exactly so that they could be used in random code without people gouging their eyes out when seeing the crazy jumble of letters that were the old internal names. As a result the drbd thing merged cleanly (commit 8d49a775: "Merge branch 'for-2.6.39/drivers' of git://git.kernel.dk/linux-2.6-block"), since there was no data conflict - but the end result obviously doesn't actually compile.
