2017-04-11iwlwifi: mvm: fix RX SKB header size and align it properlyJohannes Berg
When receiving a frame, we currently pull in sizeof(*hdr) plus some extra (crypto/snap), which is too much, most headers aren't actually sizeof(*hdr) since that takes into account the 4-address format but doesn't take into account QoS. As a result, a typical frame will have 4 bytes of the payload in the SKB header already. Fix this by calculating the correct header length, and now that we have that, align the end of the SKB header to a multiple of 4 so that the IP header will be aligned properly when pulled in.

2017-04-11iwlwifi: be more verbose about needed firmwareLuca Coelho
If the supported firmware versions are not found, we currently only print "no suitable firmware found". This is not very informative for the user trying to find the correct version to use.

2017-04-11iwlwifi: mvm: support new binding APISara Sharon
For a000 devices the binding API needs to include relevant lmac ID - support the new API. The new API should be used regardless if the device had CDB or not. If there is no actual CDB support the binding is bound to first lmac regardless of the band. There are some functionality changes in binding restrictions and quota allocations that will be handled in future patches.

2017-04-05mwifiex: catch mwifiex_fw_dpc() errors properly in resetBrian Norris
When resetting the device, we take a synchronous firmware-loading code path, which borrows a lot from the asynchronous path used at probe time. We don't catch errors correctly though, which means that in the PCIe driver, we may try to dereference the 'adapter' struct after mwifiex_fw_dpc() has freed it. See this (erronous) print in mwifiex_pcie_reset_notify(): mwifiex_dbg(adapter, INFO, "%s, successful\n", __func__); Let's instead refactor the synchronous (or "!req_fw_nowait") path so that we propagate errors and handle them properly. This fixes a use-after-free issue in the PCIe driver, as well as a misleading debug message ("successful"). It looks like the SDIO driver doesn't have these problems, since it doesn't do anything after mwifiex_reinit_sw().

2017-04-05mwifiex: fix use-after-free for FW reinit errorsBrian Norris
If we fail to reinit the FW when resetting the device (in the synchronous version of mwifiex_init_hw_fw() -> mwifiex_fw_dpc()), mwifiex_fw_dpc() will tear down the interface and free up the adapter. But we don't actually check for all failure cases of mwifiex_fw_dpc(), so some of them fall through and dereference adapter->fw_done with a freed adapter, causing a use-after-free bug. In any case, mwifiex_fw_dpc() will always signal FW completion -- in the error OR success case -- so at best, this was repeat work. Let's not do it.

This is configuring the station NSS capabilities incorreclty in the target. For example, if station advertise Rx_mcs set as 2 spatial streams in HT capabilities and 1 spatial streams in VHT capabilities in assoc request, as per current logic we are calculating nss from HT capabilities and the driver sets peer_num_spatial_streams as 2 for the station which is configured in VHT 1*1.

Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.
