Patch 1 splits out generic XDP processing into reusable parts, patch 2 implements generic cpumap support (details in commit) and patch 3 allows devmap bpf prog execution before generic_xdp_tx is called. Patch 4 just updates a couple of selftests to adapt to changes in behavior (in that specifying devmap/cpumap prog fd in generic mode is now allowed).
