[PATCH bpf-next 0/5] Bulk optimization for XDP cpumap redirect

2019-04-10 Thread Jesper Dangaard Brouer
This patchset utilize a number of different kernel bulk APIs for optimizing the performance for the XDP cpumap redirect feature. Patch-1: ptr_ring batch consume Patch-2: Send SKB-lists to network stack Patch-3: Introduce SKB helper to alloc SKB outside net-core Patch-4: kmem_cache bulk alloc of SK
