Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says: ==================== Please accept the following pull request intended for the 3.13 tree... I had intended to pass most of these to you as much as two weeks ago. Unfortunately, I failed to account for the effects of bad Internet connections and my own fatique/laziness while traveling. On the bright side, at least these have been baking in linux-next for some time! For the mac80211 bits, Johannes says: "This time I have two fixes for P2P (which requires not using CCK rates) and a workaround for APs with broken WMM information." For the iwlwifi bits, Johannes says: "I have a few fixes for warnings/issues: one from Alex, fixing scan timings, one from Emmanuel fixing a WARN_ON in the DVM driver, one from Stanislaw removing a trigger-happy WARN_ON in the MVM driver and a change from myself to try to recover when the device isn't processing commands quickly." And: "For this round, I have a lot of changes: * power management improvements * BT coexistence improvements/updates * new device support * VHT support * IBSS support (though due to a small bug it requires new firmware) * various other fixes/improvements." For the Bluetooth bits, Gustavo says: "More patches for 3.12, busy times for Bluetooth. More than a 100 commits since the last pull. The bulk of work comes from Johan and Marcel, they are doing fixes and improvements all over the Bluetooth subsystem, as the diffstat can show." For the ath10k and ath6kl bits, Kalle says: "Bartosz added support to ath10k for our 10.x AP firmware branch, which gives us AP specific features and fixes. We still support the main firmware branch as well just like before, ath10k detects runtime what firmware is used. Unfortunately the firmware interface in 10.x branch is somewhat different so there was quite a lot of changes in ath10k for this. Michal and Sujith did some performance improvements in ath10k. Vladimir fixed a compiler warning and Fengguang removed an extra semicolon." For the NFC bits, Samuel says: "It's a fairly big one, with the following highlights: - NFC digital layer implementation: Most NFC chipsets implement the NFC digital layer in firmware, but others have more basic functionalities and expect the host to implement the digital layer. This layer sits below the NFC core. - Sony's port100 support: This is "soft" NFC USB dongle that expects the digital layer to be implemented on the host. This is the first user of our NFC digital stack implementation. - Secure element API: We now provide a netlink API for enabling, disabling and discovering NFC attached (embedded or UICC ones) secure elements. With some userspace help, this allows us to support NFC payments. Only the pn544 driver currently supports that API. - NCI SPI fixes and improvements: In order to support NCI devices over SPI, we fixed and improved our NCI/SPI implementation. The currently most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode and we're planning to use our NCI/SPI framework to implement a driver for it. - pn533 fragmentation support in target mode: This was the only missing feature from our pn533 impementation. We now support fragmentation in both Tx and Rx modes, in target mode." On top of all that, brcmfmac and rt2x00 both get the usual flurry of updates. A few other drivers get hit here or there as well. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
