2012-05-18iwlwifi: dont pull too much payload in skb headEric Dumazet
As iwlwifi use fat skbs, it should not pull too much data in skb->head, and particularly no tcp data payload, or splice() is slower, and TCP coalescing is disabled. Copying payload to userland also involves at least two copies (part from header, part from fragment) Each layer will pull its header from the fragment as needed. (on 64bit arches, skb_tailroom(skb) at this point is 192 bytes) With this patch applied, I have a major reduction of collapsed/pruned TCP packets, a nice increase of TCPRcvCoalesce counter, and overall better Internet User experience. Small packets are still using a fragless skb, so that page can be reused by the driver.

2012-05-14rtlwifi: fix for race condition when firmware is cachedLarry Finger
In commit b0302ab, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data. This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

2012-05-08brcmfmac: add out of band interrupt supportFranky Lin
Some sdio host controllers do not support real in band interrupt. Software polling mode as a replacement is not fast enough for high throughput and new features. Also some in band interrupts do not support host wake up on embedded platform even when they are real physical interrupts. Therefore out of band (oob) interrupt mechanism is implemented for these scenarios. To provide oob irq number and flags used for irq registration in brcmfmac, a platform device contains irq resource must be registered in board specific code. Here is an example of platform device structure: struct resource brcmf_sdio_res[] = { { .start = GPIO_BRCMF_SDIO_OOB_NUM, .end = GPIO_BRCMF_SDIO_OOB_NUM, .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL, } }; struct platform_device brcmf_sdio_device = { .name = "brcmf_sdio_pd", .id = -1, .num_resources = ARRAY_SIZE(brcmf_sdio_res), .resource = brcmf_sdio_res, }; Reviewed-by: pieter-paul giesberts <pieterpg@broadcom.com> Reviewed-by: arend van spriel <arend@broadcom.com> Signed-off-by: franky lin <frankyl@broadcom.com> Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: John W.

2012-05-03iwlwifi: fix skb truesize underestimationEric Dumazet
By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames, but doesnt say so in skb->truesize. This makes very possible to exhaust kernel memory since these skb evade normal socket memory accounting. As struct ieee80211_hdr is going to be pulled before calling IP stack, there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes. alloc_skb() is ok in this driver, allowing more tailroom. Pull beginning of frame in skb header, in the hope we can reuse order-1 pages in the driver immediately for small frames and reduce their truesize to the minimum (linear skbs) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Wey-Yi Guy <wey-yi.w.guy@intel.com> Cc: "John W.

2012-05-02Revert "ath9k_hw: Fix incorrect spur_freq_sd for AR9003"Rajkumar Manoharan
This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8. The commit a844adfd is degrading rx sensitivity of lower rate in HT40 mode and it is confirmed that reverting the change is improving rx sensitivity. spur_freq_sd (for self-corr in AGC) is defined with respect to the center of each 20MHz channel while spur_phase_delta (for self-corr in Rx and spur data filter) is defined with respect to the center of current RF channel. So in short, we need to subtract spur_freq_sd (for self-corr in AGC) by the offset between the center of primary20 and the center of RF channel in SW. This offset could be +/10 MHz for dynamic 40.

The later call may result in a need to communicate with the chip to stop it (as it happens now if the interface is still up before rmmod), which means calls are made back to the glue, resulting in freed memory access. Fix this by freeing glue data last. Cc: stable@vger.kernel.org # v2.6.37+ Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-27b43: only reload config after successful initializationSeth Forshee
Commit 2a19032 (b43: reload phy and bss settings after core restarts) introduced an unconditional call to b43_op_config() at the end of b43_op_start(). When firmware fails to load this can wedge the system. There's no need to reload the configuration after a failed initialization anyway, so only make the call if initialization was successful.

dpc takes care of all data packets transmissions for sdio function 2. It is possible that it misses some completion events when the traffic is heavy or it's running on a slow cpu. A linked list is introduced to make sure dpc is invoked whenever needed.
