Add support for a common iWARP query port function, the new function
includes a common code that is used by the iWARP devices to update the
port attributes like max_mtu, active_mtu, state, and phys_state, the
function also includes a call for the driver-specific query_port callback
to query the device-specific port attributes.

Thanks, the qedr is also a iWARP device but it has most of the code common with
The RoCE part, so we'll need to split the code earlier between the protocols.
However, why not make the code for port-state and mtu common for Both iWARP + RoCE?

Raising a question, in some places we use the macro above and in others
rdma_protocol_iwarp(device, port_num), any reason to prefer one over the other ?

Yes, That's why I decided not to touch it.

I don't think that this is a good idea because they don't share the same
code for determining the port-state and mtu (please see mlx4/mlx5 v.s.
other iWARP drivers), while it is the same code for all iWARP drivers.

I thought it's more readable to use rdma_node_get_transport() in this
case than using rdma_protocol_iwarp().

Now that we have a common iWARP query port function we can remove the
common code from the iWARP drivers.
