Originally, after adding a RXE device successfully, the RXE device
gets ready, it still reports 'PORT_DOWN' state. Set the state to
*IB_PORT_ACTIVE* once it becomes ready to access.

IB_PORT_ACTIVE is set in the function rxe_port_up.

The followings are the call chain.

In this commit, in rxe_net_add, the port->attr.state is set to IB_PORT_ACTIVE.

But then in the function rxe_init_port_param, port->attr.state is set to IB_PORT_DOWN again.

Thanks, I guess anything got wrong in my env(virtual interface in a virtual machine), let's drop this.
