[PATCH v3 net-next 2/2] selftests: net: tcp_mmap must use TCP_ZEROCOPY_RECEIVE

After prior kernel change, mmap() on TCP socket only reserves VMA. We have to use getsockopt(fd, IPPROTO_TCP, TCP_ZEROCOPY_RECEIVE, ...) to perform the transfert of pages from skbs in TCP receive queue into such VMA. struct tcp_zerocopy_receive { __u64 address; /* in: address of
