commit b631e3a4e94c77c9007d60b577a069c203ce9594 upstream.
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features.
One of them is TCP_INQ cmsg support introduced in commit 2c9e77659a0c ("mptcp: add TCP_INQ cmsg support").
It is possible to look for "mptcp_ioctl" in kallsyms because it was needed to introduce the mentioned feature. We can skip these tests and not set TCPINQ option if the feature is not supported.
