Hi!
This series is my stab at what was discussed at a recent IOvisor
bi-weekly call. The idea is to make the device translator run at
the program load time. This makes the offload more explicit to
the user space. It also makes it easy for the device translator
to insert information into the original verifier log.
The first patch renames the ndo_xdp into ndo_bpf, because I use
it to mux the BPF program load calls. I'm not sure if that's
necessary.
Note, this RFC will not apply, the NFP patches have conflicts
both with Alexei's stack work and TC block work.
Jakub Kicinski (12):
net: bpf: rename ndo_xdp to ndo_bpf
bpf: offload: add infrastructure for loading programs for a specific
netdev
bpf: report offload info to user space
bpftool: print program device bound info
xdp: allow attaching programs loaded for specific device
cls_bpf: allow attaching programs loaded for specific device
nfp: bpf: drop support for cls_bpf with legacy actions
nfp: bpf: refactor offload logic
nfp: bpf: require seamless reload for program replace
nfp: bpf: remove the register renumbering leftovers
nfp: bpf: move to new BPF program offload infrastructure
bpf: remove old offload/analyzer
