These specific capabilities indicate the RoCE ability to use the force-loopback on its QP. When creating a QP with force-loopback enabled, the gid index is not required.

Check the capabilities of RoCE, and if it supports force-loopback while RoCE is enabled, open the QP with force-loopback capability. This will allow the QP to be immune from any gid aspects.

Till the use of force-loopback QP we didn't support RX/TX DR-steering due to a missing recovery mechanism in case the GID was changed by the user. Now when using loopback QP there is no need to worry about gid staff and we able to support RX/TX steering like it's done with FDB steering.

This series enables SW Steering RX/TX domains when force-loopback is supported while RoCE is enabled.
When using loopback QP the gid index is not required and the code is safe from any gid change scenario, this enables opening the RX/TX domains paths.
