[RFC/RFT,v2,0/3] Introduce GRO support to cpumap codebase

Message

Lorenzo Bianconi Sept. 16, 2024, 10:13 a.m. UTC

Add GRO support to cpumap codebase moving the cpu_map_entry kthread to a
NAPI-kthread pinned on the selected cpu.

Changes in rfc v2:
- get rid of dummy netdev dependency

Lorenzo Bianconi (3):
  net: Add napi_init_for_gro routine
  net: add napi_threaded_poll to netdevice.h
  bpf: cpumap: Add gro support

Oh okay, so it's still uses a NAPI.
When I'm back from the conferences (next week), I might rebase and send
the solution where I only use the GRO part of it, i.e. no
napi_schedule()/poll()/napi_complete() logics.
