Looks like the usnic provider is acting like the RoCE providers by returning
the default pkey when calling the query_pkey() callback, Do you think that
this needs to removed like what was done for iWarp providers?

int usnic_ib_query_pkey(struct ib_device *ibdev, u8 port, u16 index,
                                u16 *pkey)
{
        if (index > 0)
                return -EINVAL;

        *pkey = 0xffff;
        return 0;
}

Thanks,
