Hi, I'll post this out again to keep discussion going. Thanks all for the testing and comments so far.
Changes since the RFC https://lore.kernel.org/netdev/20230927001308.749910-1-npig...@gmail.com/ - Replace slab allocations for flow keys with expanding the use of the per-CPU key allocator to ovs_vport_receive. - Drop patch 1 with Ilya's since they did the same thing (that is added at patch 3). - Change push_nsh stack reduction from slab allocation to per-cpu buffer. - Drop the ovs_fragment stack usage reduction for now sinc it used slab and was a bit more complicated. I posted an initial version of the per-cpu flow allocator patch in the RFC thread. Since then I cleaned up some debug code and increased the allocator size to accommodate the additional user of it.
