Applied, thanks!
From: Ido Schimmel <idosch@nvidia.com> Jiri says: This is a preparation patchset for follow-up support of boards with extended mezzanine (XM), which is going to allow extended (scale-wise) router offload. XM requires a separate PRM register named XMDR to be used instead of RALUE to insert/update/remove FIB entries. Therefore, this patchset extends the previously introduces low-level ops to be able to have XM-specific FIB entry config implementation. Currently the existing original RALUE implementation is moved to "basic" low-level ops. Unlike legacy router, insertion/update/removal of FIB entries into XM could be done in bulks up to 4 items in a single PRM register write. That is why this patchset implements "an op context", that allows the future XM ops implementation to squash multiple FIB events to single register write. For that, the way in which the FIB events are processed by the work queue has to be changed. The conversion from 1:1 FIB event - work callback call to event queue is implemented in patch #3. Patch #4 introduces "an op context" that will allow in future to squash multiple FIB events into one XMDR register write. Patch #12 converts it from stack to be allocated per instance. Existing RALUE manipulations are pushed to ops in patch #10. Patch #13 is introducing a possibility for low-level implementation to have per FIB entry private memory. The rest of the patches are either cosmetics or smaller preparations.
