* RDMA/mana_ib: add support of multiple portsKonstantin Taranov2025-07-231-3/+10
| | | | | | | | | | | | If the HW indicates support of multiple ports for rdma, create an IB device with a port per netdev in the ethernet mana driver. CM is only available on port 1, but RC QPs are supported on all ports.
