On AR5008-AR9002, other forms of calibration must not be started while the noise floor calibration is running, as this can create invalid readings which were sometimes not even recoverable by any further calibration attempts. This patch also ensures that the result of noise floor measurements are processed faster and also allows the result of the initial calibration on reset to make it into the NF history buffer Signed-off-by:

The noise floor history buffer is currently not kept per channel, which can lead to problems when changing channels from a clean channel to a noisy one. Also when switching from HT20 to HT40, the noise floor history buffer is full of measurements, but none of them contain data for the extension channel, which it needs quite a bit of time to recover from. This patch puts all the per-channel calibration data into a single data structure, and gives the the driver control over whether that is used per-channel or even not used for some channels. For ath9k_htc, I decided to keep this per-channel in order to avoid creating regressions. For ath9k, the data is kept only for the operating channel, which saves some space. ath9k_hw takes care of wiping old data when the operating channel or its channel flags change. Signed-off-by:

Previously the software scan callback was used to indicate to the hardware, when it was safe to calibrate. This didn't really work properly, because it depends on a specific order of software scan callbacks vs. channel changes. Also, software scans are not the only thing that triggers off-channel activity, so it's better to use the newly added indication from mac80211 for this and not use the software scan callback for anything calibration related. This fixes at least some of the invalid noise floor readings that I've seen in AP mode on AR9160 Signed-off-by:

Writes to the analog shift registers, which are issues by the initval programming function, require a 100 usec delay (similar to AR9002, but in a different register range). Signed-off-by:

When updating the PAPRD table in hardware, PAPRD itself needs to be disabled first, otherwise the hardware can throw a data bus error, which upsets at least some platforms. Signed-off-by:

The periodic noise floor calibration is broken on this chip family, because it keeps triggering a software-filtered noise floor calibration, but never reads the result before uploading the history buffer value to the hardware. Fix this with a call to ath9k_hw_getnf(), just like on AR9002. Signed-off-by:

On AR9003 the initial noise floor calibration is currently triggered at the end of the reset without allowing the hardware to update the baseband settings. This could potentially make scans in noisy environments a bit more unreliable, so use the same calibration sequence that is used on AR9002. Signed-off-by:

Releasing the scan mutex while starting scans can lead to unexpected things happening, so we shouldn't do that. Fix that and hold the mutex across the scan triggering. Signed-off-by:

commit f84b29ec Author: Johannes Berg <johannes.berg@intel.com> Date: Tue May 18 02:29:13 2010 -0700 iwlwifi: queue user-initiated scan when doing internal scan introduced a potential deadlock because it calls ieee80211_scan_completed() with the priv->mutex held, but mac80211 may call back into iwlwifi which would lead to recursive locking. Move this out from under the mutex. Cc: stable@kernel.org Signed-off-by:

Marvell 88ec048 is a derivative of its 88e1121r device. From the programmer's perspective, the one major difference is the addition of an additional control bit in Page 2 Register 16 - used to control the padding of odd nibble preambles. This patch adds support for this new device, while inheriting as much code as possible from the existing 88e1121r implementation. Signed-off-by:

This patch addresses an issue seen on 82580 in which the MDICNFG register will be reset during a single function reset and as a result we will be unable to communicate with the PHY. To correct the issue, added a call to reset_mdicnfg just prior to the first access of the MDICNFG register in sgnii_uses_mdio. Signed-off-by:

Commit fc6055a5 (net: Introduce skb_orphan_try()) allows an early orphan of the skb and takes care on tx timestamping, which needs the sk-reference in the skb on driver level. So does the can-raw socket, which has not been taken into account here. The patch below adds a 'prevent_sk_orphan' bit in the skb tx shared info, which fixes the problem discovered by Matthias Fuchs here: http://marc.info/?t=128030411900003&r=1&w=2 Even if it's not a primary tx timestamp topic it fits well into some skb shared tx context. Or should be find a different place for the information to protect the sk reference until it reaches the driver level? Signed-off-by:

This reverts commit 15e83ed7. As explained by Johannes Berg, the optimization made here is invalid. Or, at best, incomplete. Not only destructor invocation, but conntract entry releasing must be executed outside of hw IRQ context. So just checking "skb->destructor" is insufficient. Signed-off-by:

This change corrects an issue that resulted in a null pointer dereference for the addition of VLAN 0 without any VLANs being registered. Also this code removes some unnecessary checks for defines and the unnecessary setting of VLAN flags since that is now handled within the kernel via the vlan_features. Signed-off-by:

Based on original patch/work from Jean Delvare <jdelvare@suse.de> Synchronize all IRQs when in MSI-X IRQ mode. Jean's original patch hard coded the sync with the 3 possible vectors, this patch incorporates more flexibility for the future and aligns with how igb stores the number of vectors into the adapter structure.

The pm_qos_add_request call has to register the pm_qos request with the pm_qos susbsystem before first use of the pm_qos request via pm_qos_update_request. As pm_qos changed to use plists there is no benefit in registering and unregistering the pm_qos request on ifup/ifdown and thus we move the registering into e1000_open and the unregistering in e1000_close. This fixes the following warning: [ 1.786060] WARNING: at kernel/pm_qos_params.c:264 pm_qos_update_request+0x28/0x54() [ 1.786088] Hardware name: Latitude E6500 [ 1.787045] pm_qos_update_request() called for unknown object [ 1.787966] Modules linked in: [ 1.788940] Pid: 1, comm: swapper Not tainted 2.6.35-rc5-mmotm0719 #1 [ 1.790035] Call Trace: [ 1.791121] [<ffffffff81037335>] warn_slowpath_common+0x80/0x98 [ 1.792205] [<ffffffff810373e1>] warn_slowpath_fmt+0x41/0x43 [ 1.793279] [<ffffffff81057c14>] pm_qos_update_request+0x28/0x54 [ 1.794347] [<ffffffff8134889e>] e1000_configure+0x421/0x459 [ 1.795393] [<ffffffff8134afbd>] e1000_open+0xbd/0x37c [ 1.796436] [<ffffffff8105743a>] ? raw_notifier_call_chain+0xf/0x11 [ 1.797491] [<ffffffff8145f948>] __dev_open+0xae/0xe2 [ 1.798547] [<ffffffff8145f997>] dev_open+0x1b/0x49 [ 1.799612] [<ffffffff8146e36e>] netpoll_setup+0x84/0x259 [ 1.800685] [<ffffffff81b5037c>] init_netconsole+0xbc/0x21f [ 1.801744] [<ffffffff81b5026c>] ? sir_wq_init+0x0/0x35 [ 1.802793] [<ffffffff81b502c0>] ? init_netconsole+0x0/0x21f [ 1.803845] [<ffffffff810002ff>] do_one_initcall+0x7a/0x12f [ 1.804885] [<ffffffff81b2ccae>] kernel_init+0x138/0x1c2 [ 1.805915] [<ffffffff81003554>] kernel_thread_helper+0x4/0x10 [ 1.806937] [<ffffffff81590e00>] ? restore_args+0x0/0x30 [ 1.807955] [<ffffffff81b2cb76>] ? kernel_init+0x0/0x1c2 [ 1.808958] [<ffffffff81003550>] ? kernel_thread_helper+0x0/0x10 [ 1.809958] ---[ end trace 84b562a00a60539e ]--- Signed-off-by:
