Merge branch 'bpf-allow-xdp_redirect-for-xdp-dev-bound-programs'
Lorenzo Bianconi says:
====================
bpf: Allow XDP_REDIRECT for XDP dev-bound programs
In the current implementation if the program is dev-bound to a specific
device, it will not be possible to perform XDP_REDIRECT into a DEVMAP or
CPUMAP even if the program is running in the driver NAPI context.
Fix the issue introducing __bpf_prog_map_compatible utility routine in
order to avoid bpf_prog_is_dev_bound() during the XDP program load.
Continue forbidding to attach a dev-bound program to XDP maps.
