Fix two issues in the reuseport_bpf selftests that were reported by Linaro CI: [...] + ./reuseport_bpf ---- IPv4 UDP ---- Testing EBPF mod 10... Reprograming, testing mod 5... ./reuseport_bpf: ebpf error. log: 0: (bf) r6 = r1 1: (20) r0 = *(u32 *)skb[0] 2: (97) r0 %= 10 3: (95) exit processed 4 insns : Operation not permitted + echo FAIL [...] ---- IPv4 TCP ---- Testing EBPF mod 10... ./reuseport_bpf: failed to bind send socket: Address already in use + echo FAIL [...] For the former adjust rlimit since this was the cause of failure for loading the BPF prog, and for the latter add SO_REUSEADDR.
