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.

2019-09-11net: stmmac: implement support for passive mode converters via dtAlexandru Ardelean
In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both.

2019-09-10nfp: honor FW reset and loading policiesDirk van der Merwe
The firmware reset and loading policies can be controlled with the combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'. 'app_fw_from_flash' defines which firmware should take precedence, 'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred' is selected, the management firmware makes the decision on which firmware will be loaded by comparing versions of the flash firmware and the host supplied firmware. 'abi_drv_reset' defines when the driver should reset the firmware when the driver is probed, either 'Disk' if firmware was found on disk, 'Always' reset or 'Never' reset. Note that the device is always reset on driver unload if firmware was loaded when the driver was probed. 'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on the device. Furthermore, we limit the cases to where the driver will unload firmware again when the driver is removed to only when firmware was loaded by the driver and only if this particular device was the only one that could have loaded firmware. This is needed to avoid firmware being removed while in use on multi-host platforms.

2019-09-09ixgbe: sync the first fragment unconditionallyFiro Yang
In Xen environment, if Xen-swiotlb is enabled, ixgbe driver could possibly allocate a page, DMA memory buffer, for the first fragment which is not suitable for Xen-swiotlb to do DMA operations. Xen-swiotlb have to internally allocate another page for doing DMA operations. This mechanism requires syncing the data from the internal page to the page which ixgbe sends to upper network stack. However, since commit f3213d932173 ("ixgbe: Update driver to make use of DMA attributes in Rx path"), the unmap operation is performed with DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed. Since the sync isn't performed, the upper network stack could receive a incomplete network packet. By incomplete, it means the linear data on the first fragment(between skb->head and skb->end) is invalid. So we have to copy the data from the internal xen-swiotlb page to the page which ixgbe sends to upper network stack through the sync operation. More details from Alexander Duyck: Specifically since we are mapping the frame with DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result a sync is not performed on an unmap and must be done manually as we skipped it for the first frag. As such we need to always sync before possibly performing a page unmap operation.

2019-09-09i40e: Remove EMPR traces from debugfs facilityMauro S. M. Rodrigues
Since commit '5098850c9b9b ("i40e/i40evf: i40e_register.h updates")' it is no longer possible to trigger an EMP Reset from debugfs, but it's possible to request it either way, to end up with a bad reset request: echo empr > /sys/kernel/debug/i40e/0002\:01\:00.1/command i40e 0002:01:00.1: debugfs: forcing EMPR i40e 0002:01:00.1: bad reset request 0x00010000 So let's remove this piece of code and show the available valid commands as it is when any invalid command is issued.
