From: Geliang Tang <tanggeliang@xxxxxxxxxx> Currently, bpf_skc_to_mptcp_sock() helper is not allowed to be used in cg_sockopt. This patch adds this permission. Thanks to the previous patch allowing skc_to_mptcp_sock() to be used with MPTCP sockets, this permission allows this helper to be use it in CGroup BPF hooks, e.g. [gs]etsocktopt.
