* RDMA/mana_ib: add support of multiple portsKonstantin Taranov2025-07-233-55/+69
| | | | | | | | | | | | 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.

| * RDMA: Pass entire uverbs attr bundle to create cq functionAkiva Goldberger2024-06-272-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes the create_cq verb signature by sending the entire uverbs attr bundle as a parameter. This allows drivers to send driver specific attrs through ioctl for the create_cq verb and access them in their driver specific code. Also adds a new enum value for driver specific ioctl attributes for methods already supporting UHW.
