commit41e684ef3fupstream. Until now the flex parser capability was used in ib_query_device() to indicate tunnel_offloads_caps support for mpls_over_gre/mpls_over_udp. Newer devices and firmware will have configurations with the flexparser but without mpls support. Testing for the flex parser capability was a mistake, the tunnel_stateless capability was intended for detecting mpls and was introduced at the same time as the flex parser capability. Otherwise userspace will be incorrectly informed that a future device supports MPLS when it does not.
