Subject: libbpf: Add SEC name for xdp programs attached to CPUMAP
Patch-mainline: v5.9-rc1
Git-commit: 4be556cf5aef416904743f2cee689351f91445b6
References: bsc#1177028
As for DEVMAP, support SEC("xdp_cpumap/") as a short cut for loading
the program with type BPF_PROG_TYPE_XDP and expected attach type
BPF_XDP_CPUMAP.
