From: Eric Dumazet <edumazet@xxxxxxxxxx>
getsockopt() or setsockopt() sometimes returns -EINTR instead of
-ENOPROTOOPT, causing headaches to application developers.
This is because unsupported commands might go through nf_sockopt_find()
and this function returns -EINTR instead of -ERESTARTSYS if
a signal is pending.
