Merge branch 'bpf-offload-sharing'

Jakub Kicinski says:

====================
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.
