2019-09-16ixgbe: fix xdp handle calculationsCiara Loftus
Commit 7cbbf9f1fa23 ("ixgbe: fix xdp handle calculations") reintroduced the addition of the umem headroom to the xdp handle in the ixgbe_zca_free, ixgbe_alloc_buffer_slow_zc and ixgbe_alloc_buffer_zc functions. However, the headroom is already added to the handle in the function ixgbe_run_xdp_zc. This commit removes the latter addition and fixes the case where the headroom is non-zero.

2019-09-16net: stmmac: socfpga: re-use the `interface` parameter from platform dataAlexandru Ardelean
The socfpga sub-driver defines an `interface` field in the `socfpga_dwmac` struct and parses it on init. The shared `stmmac_probe_config_dt()` function also parses this from the device-tree and makes it available on the returned `plat_data` (which is the same data available via `netdev_priv()`). All that's needed now is to dig that information out, via some `dev_get_drvdata()` && `netdev_priv()` calls and re-use it.

2019-09-16net/wan: dscc4: remove broken dscc4 driverDan Carpenter
Using static analysis, I discovered that the "dpriv->pci_priv->pdev" pointer is always NULL. This pointer was supposed to be initialized during probe and is essential for the driver to work. It would be easy to add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver has been broken since before we started using git and no one has complained so probably we should just remove it.

2019-09-13cdc_ether: fix rndis support for Mediatek based smartphonesBjørn Mork
A Mediatek based smartphone owner reports problems with USB tethering in Linux. The verbose USB listing shows a rndis_host interface pair (e0/01/03 + 10/00/00), but the driver fails to bind with [ 355.960428] usb 1-4: bad CDC descriptors The problem is a failsafe test intended to filter out ACM serial functions using the same 02/02/ff class/subclass/protocol as RNDIS. The serial functions are recognized by their non-zero bmCapabilities. No RNDIS function with non-zero bmCapabilities were known at the time this failsafe was added. But it turns out that some Wireless class RNDIS functions are using the bmCapabilities field. These functions are uniquely identified as RNDIS by their class/subclass/protocol, so the failing test can safely be disabled. The same applies to the two types of Misc class RNDIS functions. Applying the failsafe to Communication class functions only retains the original functionality, and fixes the problem for the Mediatek based smartphone. Tow examples of CDC functional descriptors with non-zero bmCapabilities from Wireless class RNDIS functions are: 0e8d:000a Mediatek Crosscall Spider X5 3G Phone CDC Header: bcdCDC 1.10 CDC ACM: bmCapabilities 0x0f connection notifications sends break line coding and serial state get/set/clear comm features CDC Union: bMasterInterface 0 bSlaveInterface 1 CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 and 19d2:1023 ZTE K4201-z CDC Header: bcdCDC 1.10 CDC ACM: bmCapabilities 0x02 line coding and serial state CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 CDC Union: bMasterInterface 0 bSlaveInterface 1 The Mediatek example is believed to apply to most smartphones with Mediatek firmware.

2019-09-13rtw88: 8822c: add SW DPK supportTzu-En Huang
Power amplifiers are not linear components, and require DPK to reduce its nonlinearity. DPK is called Digital Pre-distortion Calibration, can be used to compensate the output of power. DPK tracking is in charge of tracking the thermal changes. And it then shifts the power curve accordingly, which makes the power output remains linear even if the PA works in different temperature. To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate.

Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get.

Updates the iavf driver to only apply the MAC address change when the PF ACK's the requested change. Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call instead of the driver accessing the queue mapping directly. Jake updates i40e to use ktime_get_real_ts64() instead of ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud filters, since it is a reserved bit and not a valid type. Also added code comments to clearly state which bits are reserved and should not be used or defined for cloud filter adminq command. Clarify the macros used to specify the cloud filter fields are individual bits, so use the BIT() macro. Aleksandr fixes up the print_link_message() to include the "negotiated" FEC status for i40e. Czeslaw also adds additional log message for devices without FEC in the print_link_message() for i40e. Colin Ian King reduces the object code size by making the array API static constant.

2019-09-13brcmfmac: don't realloc wiphy during PCIe resetRafał Miłecki
Providing a new wiphy on every PCIe reset was confusing and was causing configuration problems for some users (supplicant and authenticators). Sticking to the existing wiphy should make error recovery much simpler and more reliable.

2019-09-13brcmfmac: split brcmf_attach() and brcmf_detach() functionsRafał Miłecki
Move code allocating/freeing wiphy out of above functions. This will allow reinitializing the driver (e.g. on some error) without allocating a new wiphy.

2019-09-13brcmfmac: move "cfg80211_ops" pointer to another structRafał Miłecki
This moves "ops" pointer from "struct brcmf_cfg80211_info" to the "struct brcmf_pub". This movement makes it possible to allocate wiphy without attaching cfg80211 (brcmf_cfg80211_attach()). It's required for later separation of wiphy allocation and driver initialization. While at it fix also an unlikely memory leak in the brcmf_attach().

2019-09-12ice: Enable DDP package downloadTony Nguyen
Attempt to request an optional device-specific DDP package file (one with the PCIe Device Serial Number in its name so that different DDP package files can be used on different devices). If the optional package file exists, download it to the device. If not, download the default package file. Log an appropriate message based on whether or not a DDP package file exists and the return code from the attempt to download it to the device. If the download fails and there is not already a package file on the device, go into "Safe Mode" where some features are not supported.

2019-09-12ice: Initialize DDP package structuresTony Nguyen
Add functions to initialize, parse, and clean structures representing the DDP package. Upon completion of package download, read and store the DDP package contents to these structures. This configuration is used to identify the default behavior and later used to update the HW table entries.

2019-09-12ice: Implement Dynamic Device Personalization (DDP) downloadTony Nguyen
Add the required defines, structures, and functions to enable downloading a DDP package. Before download, checks are performed to ensure the package is valid and compatible. Note that package download is not yet requested by the driver as further initialization is required to utilize the package.
