[PATCH v2 0/2] bpf: fix reuse of DEVMAP

[Yureka Lilian <yuka@xxxxxxxx>]

This patch series includes the previous fix to libbpf for re-using DEVMAP
maps, but modifies it to preserve compatibility with older kernels, thanks
to the feedback given by Martin KaFai Lau.

Additionally adds a basic selftest covering the re-use of DEVMAP maps, as
requested by Eduard Zingerman.
