2017-09-03mlxsw: spectrum_router: Support IPv4 underlay decapPetr Machata
Unlike encapsulation, which is represented by a next hop forwarding to an IPIP tunnel, decapsulation is a type of local route. It is created for local routes whose prefix corresponds to the local address of one of offloaded IPIP tunnels. When the tunnel is removed (i.e. all the encap next hops are removed), the decap offload is migrated back to a trap for resolution in slow path. This patch assumes that decap route is already present when encap route is added. A follow-up patch will fix this issue. Note that this patch only supports IPv4 underlay. Support for IPv6 underlay will be subject to follow-up work apart from this patchset.

2017-09-03mlxsw: spectrum_router: Support IPv4 overlay encapPetr Machata
This introduces some common code for tracking of offloaded IP-in-IP tunnels, and support for offloading IPv4 overlay encapsulating routes in particular. A follow-up patch will introduce IPv6 overlay as well. Offloaded tunnels are kept in a linked list of mlxsw_sp_ipip_entry objects hooked up in mlxsw_sp_router. A network device that represents the tunnel is used as a key to look up the corresponding IPIP entry. Note that in the future, more general keying mechanism will be needed, because parts of the tunnel information can be provided by the route. IPIP entries are reference counted, because several next hops may end up using the same tunnel, and we only want to offload it once. Encapsulation path hooks into next hop handling. Routes that forward to a tunnel are now considered gateway routes, thus giving them the same treatment that other remote routes get. An IPIP next hop type is introduced. Details of individual tunnel types are kept in an array of mlxsw_sp_ipip_ops objects. If a tunnel type doesn't match any of the known tunnel types, the next-hop is not considered an IPIP next hop. The list of IPIP tunnel types is currently empty, follow-up patches will add support for GRE. Traffic to IPIP tunnel types that are not explicitly recognized by the driver traps and is handled in slow path.

2017-09-03mlxsw: spectrum_router: Make nexthops typedPetr Machata
In the router, some next hops may reference an encapsulating netdevice, such as GRE or IPIP. To properly offload these next hops, mlxsw needs to keep track of whether a given next hop is a regular Ethernet entry, or an IP-in-IP tunneling entry. To facilitate this book-keeping, add a type field to struct mlxsw_sp_nexthop. There is, as of this patch, only one next hop type: MLXSW_SP_NEXTHOP_TYPE_ETH. Follow-up patches will introduce the IP-in-IP variant. There are several places where next hops are initialized in the IPv4 path. Instead of replicating the logic at every one of them, factor it out to a function mlxsw_sp_nexthop4_type_init(). The corresponding fini is actually protocol-neutral, so put it to mlxsw_sp_nexthop_type_fini(), but create a corresponding protocoled _fini function that dispatches to the protocol-neutral one. The IPv6 path is simpler, but for symmetry with IPv4, create the same suite of functions with corresponding logic.

2017-09-03net: mvpp2: fix use of the random mac address for PPv2.2Antoine Tenart
The MAC retrieval logic is using a variable to store an h/w stored mac address and checks this mac against invalid ones before using it. But the mac address is only read from h/w when using PPv2.1. So when using PPv2.2 it defaults to its init state. This patches fixes the logic to only check if the h/w mac is valid when actually retrieving a mac from h/w.

2017-09-03net: mvpp2: move the mac retrieval/copy logic into its own functionAntoine Tenart
The MAC retrieval has a quite complicated logic (which is broken). Moves it to its own function to prepare for patches fixing its logic, so that reviews are easier. Signed-off-by: Antoine Tenart <antoine.tenart@free-electrons.com> Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "This is a big pull request. Of note is that I'm sending you the new ioctl API for the rdma subsystem. We put it up on linux-api@, but didn't get much response. The API is complex, but it solves two different problems in one go: 1) The bi-directional nature of the RDMA file write calls, which created the security hole we had to handle (and for which the fix is now causing problems for systems in production, we were a bit over zealous in the fix and the ability to open a device, then fork, then create new queue pairs on the device and use them is broken). 2) The bloat caused by different vendors implementing extensions to the base verbs API. Each vendor's hardware is slightly different, and the hardware might be suitable for one extension but not another. By the time we add generic extensions for all the different ways that the different hardware can offload things, the API becomes bloated. Things like our completion structs have started to exceed a cache line in size because of all the elements needed to support this. That in turn shows up heavily in the performance graphs with a noticable drop in performance on 100Gigabit links as our completion structs go from occupying one cache line to 1+. This API makes things like the completion structs modular in a very similar way to netlink so that your structs can only include the items needed for the offloads/features you are actually using on a given queue pair. In that way we support everything, but only use what we need, and our structs stay smaller. The ioctl API is better explained by the posting on linux-api@ than I can explain it here, so I'll just leave it at that. The rest of the pull request is typical stuff.
