Since no skb will be mapped for RX and TX at the same time we can simply shortcut the check for SKBDESC_DMA_MAPPED_TX. Signed-off-by:

This patch updates IEEE802.11 mesh constants to be consistent with newly approved values. It modifies some values, as well as adds many new constants in preparation for updating mesh code to the current 802.11s drafts. ANA numbers were taken from: https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls A few notes are in order: 1. This will break backwards compatibility with existing Linux kernels as over-the-air constants have changed. 2. Some old and obsolete constants have been retained for now as the mesh code itself hasn't been updated yet to the new 802.11s draft. This was desired to keep the existing mesh scheme working until it can be updated. Adding the approved values is the first step in updating the mesh code. 3. Obsolete constants have been clearly marked. 4. All ANA approved 802.11s constants have been added. Signed-off-by:

Results for the active channel are updated whenever a new survey dump is requested, the old data is kept to allow multiple processes to make their own channel utilization averages. All other channels only contain the data for the last time that the hardware was on the channel, i.e. the last scan result or other off-channel activity. Running a background scan does not clear the data for the active channel. Signed-off-by:

Several serve threading problems in the current release reorder timer implementation have been discovered. A lengthy discussion - which lists some of the pitfalls and possible solutions - can be found at: http://marc.info/?t=128635927000001 But due to the complicated nature of the subject and the imminent advent of a new -rc cycle, it was decided to disable the feature for the time being.

This patch not only fixes a null-pointer de-reference that would be triggered by a PLINK_OPEN frame with mis- matching/incompatible mesh configuration, but also responds correctly to non-compatible PLINK_OPEN frames by generating a PLINK_CLOSE with the right reason code. The original bug was detected by smatch. ( http://repo.or.cz/w/smatch.git ) net/mac80211/mesh_plink.c +574 mesh_rx_plink_frame(168) error: we previously assumed 'sta' could be null.

This reverts commit 5a254ffe. The commit failed to take into account that allocated wireless devices (wiphys) are not added into the device list upon allocation, but only when they are registered. Therefore, it opened up a race between allocating and registering a name, so that if two processes allocate and register concurrently ("alloc, alloc, register, register" rather than "alloc, register, alloc, register") the code will attempt to use the same name twice.

Enable runtime PM for the wl1271 SDIO device. We request power whenever the WLAN interface is brought up, and release it after the WLAN interface is taken down. As a result, power is released immediately after probe returns, since at that point power has not been explicitly requested yet (i.e. the WLAN interface is still down). Signed-off-by:

6000g2 devices need to have temperature offset calibration. The runtime uCode needs to receive the calibration results just like BB and LO calibration. To do this, driver reads the offset value from NVM and send it to uCode after runtime uCode is alive. Signed-off-by:

iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as the chain noise reset calibration index and IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain calibration index, if not specified by the TLV value in the new firmware format. However, this is broken if we need to add more calibrations like the temperature offset calibration because we increased IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1. To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE and use it as the calibration index instead. We still keep the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for the TLV value given by ucode. Signed-off-by:

The set_pwr_src operation is only ever used from within the same sub-driver that it is declared in, so it can just be called directly instead of being an operation. Also, it is never called to set the power source to V_aux, so change the two functions accordingly (but keep the V_aux code for documentation purposes in a comment). Signed-off-by:

This operation is only ever called from set_hw_params, which is also already based on the config/ops, so that there's no need to have a separate set_ct_kill op and we can just call the right ct_threshold function. Signed-off-by:

By duplicating a little bit of code between 3945 and agn, we can move a lot of code into an agn specific station management file and thus reduce the amount of code in core that is dead to 3945. before: text data bss dec hex filename 212886 3872 96 216854 34f16 iwlcore.ko 620542 10448 304 631294 9a1fe iwlagn.ko 314013 3264 196 317473 4d821 iwl3945.ko after: text data bss dec hex filename 202857 3872 92 206821 327e5 iwlcore.ko 629102 10448 308 639858 9c372 iwlagn.ko 314240 3264 196 317700 4d904 iwl3945.ko delta: -10029 iwlcore.ko 8560 iwlagn.ko 227 iwl3945.ko so it's a net win even if you have both loaded, likely because a lot of EXPORT_SYMBOLs go away.
