Hi!
This patchset adds support for sharing BPF objects within one ASIC.
This will allow us to reuse of the same program on multiple ports of
a device leading to better code store utilization. It also enables
sharing maps between programs attached to different ports of a device.
v2:
- rename bpf_offload_match() to bpf_offload_prog_map_match();
- add split patches 7 into 5, 7 and 8.
Jakub Kicinski (11):
netdevsim: add switch_id attribute
netdevsim: add shared netdevsim devices
netdevsim: associate bound programs with shared dev
nfp: add .ndo_init() and .ndo_uninit() callbacks
bpf: offload: rename bpf_offload_dev_match() to
bpf_offload_prog_map_match()
bpf: offload: aggregate offloads per-device
bpf: offload: keep the offload state per-ASIC
bpf: offload: allow program and map sharing per-ASIC
netdevsim: allow program sharing between devices
nfp: bpf: allow program sharing within ASIC
selftests/bpf: add test for sharing objects between netdevs
