    Infiniband endport context query.

Parameter:
    policy          The policy to query.

Keyword Parameters/Class attributes:
    name            The name of the network interface to match.
    name_regex      If true, regular expression matching will
                    be used for matching the name.
    port            The port number to match.
    user            The criteria to match the context's user.
    user_regex      If true, regular expression matching
                    will be used on the user.
    role            The criteria to match the context's role.
    role_regex      If true, regular expression matching
                    will be used on the role.
    type_           The criteria to match the context's type.
    type_regex      If true, regular expression matching
                    will be used on the type.
    range_          The criteria to match the context's range.
    range_subset    If true, the criteria will match if it is a subset
                    of the context's range.
    range_overlap   If true, the criteria will match if it overlaps
                    any of the context's range.
    range_superset  If true, the criteria will match if it is a superset
                    of the context's range.
    range_proper    If true, use proper superset/subset operations.
                    No effect if not using set operations.
