Merge branch 'device-ops-as-cb'
Quentin Monnet says:
====================
For passing device functions for offloaded eBPF programs, there used to
be no place where to store the pointer without making the non-offloaded
programs pay a memory price.
As a consequence, three functions were called with ndo_bpf() through
specific commands. Now that we have struct bpf_offload_dev, and since none
of those operations rely on RTNL, we can turn these three commands into
hooks inside the struct bpf_prog_offload_ops, and pass them as part of
bpf_offload_dev_create().
This patch set changes the offload architecture to do so, and brings the
relevant changes to the nfp and netdevsim drivers.
