For AF_VSOCK, zerocopy tx mode depends on transport, so this option must be set in AF_VSOCK implementation where transport is accessible (if transport is not set during setting SO_ZEROCOPY: for example socket is not connected, then SO_ZEROCOPY will be enabled, but once transport will be assigned, support of this type of transmission will be checked). To handle SO_ZEROCOPY, AF_VSOCK implementation uses SOCK_CUSTOM_SOCKOPT bit, thus handling SOL_SOCKET option operations, but all of them except SO_ZEROCOPY will be forwarded to the generic handler by calling 'sock_setsockopt()'.
