2017-10-22nfp: use struct fields for 8 bit-wide accessPieter Jansen van Vuuren2-74/+39
Use direct access struct fields rather than PREP_FIELD() macros to manipulate the jump ID and length, both of which are exactly 8-bits wide. This simplifies the code somewhat.

2017-10-22drivers, net, mlx5: convert fs_node.refcount from atomic_t to refcount_tElena Reshetova2-15/+16
atomic_t variables are currently used to implement reference counters with the following properties: - counter is initialized to 1 using atomic_set() - a resource is freed upon counter reaching zero - once counter reaches zero, its further increments aren't allowed - counter schema uses basic atomic operations (set, inc, inc_not_zero, dec_and_test, etc.) Such atomic variables should be converted to a newly provided refcount_t type and API that prevents accidental counter overflows and underflows. This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable fs_node.refcount is used as pure reference counter. Convert it to refcount_t and fix up the operations.

2017-10-20net: sh_eth: implement R-Car Gen[12] fallback compatibility stringsSimon Horman1-0/+2
Implement fallback compatibility strings for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme is being adopted for drivers for Renesas SoCs. Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2.

The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2. Also rename sh_eth_set_rate_r8a777x as sh_eth_set_rate_rcar as it it is used by the R-Car generations supported by the driver. This patch should have no run-time effect and is compile-tested only.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-10-17 This series contains updates to i40e and ethtool. Alan provides most of the changes in this series which are mainly fixes and cleanups. Renamed the ethtool "cmd" variable to "ks", since the new ethtool API passes us ksettings structs instead of command structs. Cleaned up an ifdef that was not accomplishing anything. Added function header comments to provide better documentation. Fixed two issues in i40e_get_link_ksettings(), by calling ethtool_link_ksettings_zero_link_mode() to ensure the advertising and link masks are cleared before we start setting bits. Cleaned up and fixed code comments which were incorrect. Separated the setting of autoneg in i40e_phy_types_to_ethtool() into its own conditional to clarify what PHYs support and advertise autoneg, and makes it easier to add new PHY types in the future. Added ethtool functionality to intersect two link masks together to find the common ground between them. Overhauled i40e to ensure that the new ethtool API macros are being used, instead of the old ones. Fixed the usage of unsigned 64-bit division which is not supported on all architectures. Sudheer adds support for 25G Active Optical Cables (AOC) and Active Copper Cables (ACC) PHY types. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-10-18fsl/fman: add dpaa in module namesMadalin Bucur1-6/+6
This change just renames the FMan driver modules, using a common prefix for the DPAA FMan and DPAA Ethernet drivers. Besides making the names more aligned, this allows writing udev rules that match on either driver name, if needed, using the fsl_dpaa_* prefix. The change of netdev dev required for the DSA probing makes the previous rules written using this prefix fail, this change makes them work again, ensuring backwards compatibility for their users.
