2019-11-15mlx5: reject unsupported external timestamp flagsJacob Keller
Fix the mlx5 core PTP support to explicitly reject any future flags that get added to the external timestamp request ioctl. In order to maintain currently functioning code, this patch accepts all three current flags. This is because the PTP_RISING_EDGE and PTP_FALLING_EDGE flags have unclear semantics and each driver seems to have interpreted them slightly differently.

2019-11-15net: reject PTP periodic output requests with unsupported flagsJacob Keller
Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

There is a race in the TUN driver between napi_busy_loop and napi_gro_frags.

2019-11-15net: dsa: ocelot: add driver for Felix switch familyVladimir Oltean
This supports an Ethernet switching core from Vitesse / Microsemi / Microchip (VSC9959) which is part of the Ocelot family (a brand name), and whose code name is Felix. The switch can be (and is) integrated on different SoCs as a PCIe endpoint device. The functionality is provided by the core of the Ocelot switch driver (drivers/net/ethernet/mscc). In this regard, the current driver is an instance of Microsemi's Ocelot core driver, with a DSA front-end. It inherits its name from VSC9959's code name, to distinguish itself from the switchdev ocelot driver. The patch adds the logic for probing a PCI device and defines the register map for the VSC9959 switch core, since it has some differences in register addresses and bitfield mappings compared to the other Ocelot switches (VSC7511, VSC7512, VSC7513, VSC7514). The Felix driver declares the register map as part of the "instance table". Currently the VSC9959 inside NXP LS1028A is the only instance, but presumably it can support other switches in the Ocelot family, when used in DSA mode (Linux running on the external CPU, and not on the embedded MIPS). In a few cases, some h/w operations have to be done differently on VSC9959 due to missing bitfields. This is the case for the switch core reset and init. Because for this operation Ocelot uses some bits that are not present on Felix, the latter has to use a register from the global registers block (GCB) instead. Although it is a PCI driver, it relies on DT bindings for compatibility with DSA (CPU port link, PHY library). It does not have any custom device tree bindings, since we would like to minimize its dependency on device tree though.

2019-11-15net: mscc: ocelot: adjust MTU on the CPU port in NPI modeVladimir Oltean

2019-11-15mlxsw: spectrum_router: Allocate discard adjacency entry when neededIdo Schimmel
Commit 0c3cbbf96def ("mlxsw: Add specific trap for packets routed via invalid nexthops") allocated an adjacency entry during driver initialization whose purpose is to discard packets hitting the route pointing to it. These adjacency entries are allocated from a resource called KVD linear (KVDL). There are situations in which the user can decide to set the size of this resource (via devlink-resource) to 0, in which case the driver will not be able to load. Therefore, instead of pre-allocating this adjacency entry, simply allocate it only when needed. A variable indicating the validity of the entry is added and is used to ensure it is only allocated and written once and that it is freed after all the routes were flushed.
