2012-05-18iwlwifi: dont pull too much payload in skb headEric Dumazet1-1/+6
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.

2012-05-16iwlwifi: disable default wildcard ssid scanDavid Spinadel2-11/+24
iwl_fill_probe_request has used to add a wildcard ssid IE to any probe request template, now it's disabled and it will send wildcard ssid only for full scan. Instead, the highest priority ssid is set to the template. Due to adding high priority SSID to the template, it reduce IE len, but since we had only 260 bytes for IEs before changing allocation size to be dynamic, now we should have a bit more room for IEs.

Allocate scan command with dynamic size based on uCode capability and num of channels. This isn't an important fix as the previous allocation was always too large as it added the scan command size but later subtracted it (which meant it was supposed to be part of the max scan size.)

In e1000e a conflict arose in the validation code for settings of adapter->itr. 'net-next' had more sophisticated logic so that logic was used. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-03iwlwifi: fix skb truesize underestimationEric Dumazet3-8/+17
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.

2012-04-24iwlwifi: fix hardware queue programmingJohannes Berg2-8/+43
Newer devices have 20 (5000 series) or 30 (6000 series) hardware queues, rather than the 16 that 4965 had. This was added to the driver a long time ago, but improperly: the queue registers for the higher queues aren't just continuations of the registers for the first 16 queues, they are in other places. Therefore, the hardware would lock up when trying to activate queue 16 or above and the device would have to be restarted. Thanks goes to Emmanuel who identified this and told me how the queue programming should be done. Note that we don't use queues 20 and higher today and doing so needs more work than this.
