Daniel Xu c313eae739 bpf: selftests: Add defrag selftests ... These selftests tests 2 major scenarios: the BPF based defragmentation can successfully be done and that packet pointers are invalidated after calls to the kfunc. The logic is similar for both ipv4 and ipv6. In the first scenario, we create a UDP client and UDP echo server. The the server side is fairly straightforward: we attach the prog and simply echo back the message. The on the client side, we send fragmented packets to and expect the reassembled message back from the server.
