exthop init and de-init functions both have symmetric parts concerned with the reflection of the neighbour entry into the device's adjacency table, in case it's used by a gatewayed route. These sections of code also need to be called when a nexthop is marked as valid / invalid following NH_{ADD,DEL} events. Break these out into appropriate functions, so that they could be invoked following the reception of above events.

Miller <davem@davemloft.net> 2017-02-08mlxsw: spectrum_router: Remove FIB info from FIB entry structIdo Schimmel1-3/+1 After the previous changes, the FIB info is embedded in every nexthop group struct, which in turn is embedded in every FIB entry struct. We can therefore safely remove the FIB info from the entry struct. This has the added advantage of making the router-related structs more generic and suitable for use with IPv6 offloads.

Miller <davem@davemloft.net> 2017-02-08mlxsw: spectrum_router: Store routes in a more generic wayIdo Schimmel1-13/+27 Up until now, the only FIB entries that were associated with a nexthop group were routes to remote networks where all the nexthop devices had a valid router interface (RIF). This is in contrast to the FIB code, where all the routes are associated with a FIB info. The same design choice needs to be applied to the driver's cache. Based on the NH_{ADD,DEL} events which will be added later in the patchset, we need to be able to change the action (forward / trap) associated with all the routes using the nexthop group. However, if we can't link between the nexthop and the routes using it, then the above is impossible.

Miller <davem@davemloft.net> 2017-02-08mlxsw: spectrum_router: Add gateway indication to nexthop groupIdo Schimmel1-1/+8 The next patch is going to generalize the way in which we store routes. Instead of attaching a nexthop group only to gatewayed routes, one will be attached to each route, in a similar way to the way the FIB code stores its routes. The above means that any function operating on a nexthop group cannot assume the group represents only gatewayed nexthops. One such function is the one that refreshes a nexthop group and updates the adjacency table following nexthop changes. For a nexthop group that doesn't represent any gateways this function would essentially be a NOP, but it would be useful if it did update the action associated with any route using it. This will allow us to later consolidate code paths when a nexthop changes following NH_{ADD,DEL} events.

Miller <davem@davemloft.net> 2017-02-08mlxsw: spectrum_router: Use nexthop's scope to set action typeIdo Schimmel1-1/+1 We currently use the scope of the FIB info to distinguish between a direct unicast route and a gatewayed one. However, the kernel is perfectly happy to configure a route with scope UNIVERSE to a directly connected network. Instead, we can rely on the first nexthop's scope to check if the route is gatewayed or not.

Based on these events we need to be able to add or remove the nexthop from the device's tables. Therefore, store the private nexthop structs in a hash table and use the kernel's fib_nh struct as the key, so that we'll be able to easily find them when the events are received.

Miller <davem@davemloft.net> 2017-02-08mlxsw: spectrum_router: Store nexthop groups in a hash tableIdo Schimmel2-52/+54 Currently, when we're notified about a new RTN_UNICAST route we perform a lookup on the nexthop group list looking for a group with a matching configuration to that found in the FIB info. This is quite inefficient. Instead, we can simply rely on the kernel to consolidate several FIB configurations into the same FIB info and use the FIB info as the key for our private nexthop group struct.

This makes the nexthop de-init function symmetric with its init and also ensures nobody will try to access the neighbour entry.
