* nlmon: use standard rtnetlink link api for add/del devicesJiri Pirko2013-07-021-21/+28
| | | | | | | | | It is not nice when netdev is created right after module load and with some implicit name. So rather change nlmon to use standard rtnl link API.

* net: cdc_ether: allow combined control and data interfaceBjørn Mork2013-07-021-5/+17
| | | | | | | | | | | | | | | | | Some Icera based Huawei modems handled by this driver are not completely CDC ECM compliant, using the same USB interface for both control and data. The CDC functional descriptors include a Union naming this interface as both master and slave, so it is supportable by relaxing the descriptor parsing in case these interfaces are identical. This has been tested on a Huawei K3806 and verified to add support for that device.

| | | | | | | | | | | | bnx2x did not set dump->version in its .get_dump_flag() method. Let's set it to BNX2X_DUMP_VERSION.

* bnx2x: remove zeroing of dump data bufferMichal Schmidt2013-07-021-2/+0
| | | | | | | | | | | | There is no need to initialize the dump data with zeros. data is allocated with vzalloc, so it's already zero-filled. More importantly, the memset is harmful, because dump->len (the length requested by userspace) can be bigger than the allocated buffer (whose size is determined by asking the driver's .get_dump_flag method).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for two cpu's to race creating vxlan device. For most cases this is harmless, but the ability to assign "next avaliable vxlan device" relies on rtnl lock being held across the whole operation. Therfore two instances of calling: ip li add vxlan%d vxlan ... could collide and create two devices with same name. To fix this defer creation of socket to a work queue, and handle possible races there. Introduce a lock to ensure that changes to vxlan socket hash list is SMP safe.

Linville says: ==================== Yet one more pull request for wireless updates intended for 3.11... For the mac80211 bits, Johannes says: "Here we have a few memory leak fixes related to BSS struct handling mostly from Ben, including a fix for a more theoretical problem (associating while a BSS struct times out) from myself, a compilation warning fix from Arend, mesh fixes from Thomas, tracking the beacon bitrate (Alex), a bandwidth change event fix (Ilan) and some initial work for 5/10 MHz channels from Simon." Regarding the iwlwifi bits, Johannes says: "Emmanuel removed some unneeded/unsupported module parameters and adds a Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have an older patch to add low-power receive support, this depended on a mac80211 commit that only just came in with the merge from wireless-next I did. Ilan made beacon timings better, and Eytan added some debug statements for thermal throttling. I have a few cleanups, a fix for a long-standing but rare warning, and, arguably the most important patch here, the firmware API version bump for the 7260/3160 devices." Also included is a Bluetooth pull -- Gustavo says: "Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes on the move of the Discovery to use the new request framework. Other than that Johan provided a bunch of fixes to the L2CAP code. The rest are just small fixes and clean ups." On top of all that, there are a variety of updates and fixes to brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and there. This also includes a pull of the wireless tree, in order to prevent some merge conflicts. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the code of the receive path some code was dealing with how things were done in older kernels. Not really needed for an upstream driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the receive path a spinlock is taken upon parsing the TLV signal header. This moves to locking to the TLV handling functions where it protects the data structures.

| | * | | brcmfmac: tag packet in the netdev transmit callbackArend van Spriel2013-06-271-82/+48

Determine the tag in the netdev transmit callback instead of determining the tag just before transfer to the device. This reduces the number of exception flows and hence makes the driver code simpler.

| | * | | brcmfmac: add broken scatter-gather DMA supportFranky Lin2013-06-271-11/+67

This patch introduces an intermediate buffer list to support this kind of platform. It decreases the throughput because of an extra memcpy in critical data path. So don't turn this on unless it's necessary.
