Subject: RE: [EXTERNAL] Re: [Patch v5 0/5] RDMA/mana_ib

I have updated the last patch to use xarray, will post the update patch. We currently use aux bus for ib device. Gd_register_device is firmware specific. All the patches use RDMA/mana_ib format which is aligned with drivers/infiniband/hw/mana/ .

Thanks
