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

Change from v4:
Send qp fatal error event to the context that created the qp. Add
lookup table for qp.

Ajay Sharma (5):
  RDMA/mana_ib : Rename all mana_ib_dev type variables to mib_dev
  RDMA/mana_ib : Register Mana IB  device with Management SW
  RDMA/mana_ib : Create adapter and Add error eq
  RDMA/mana_ib : Query adapter capabilities
  RDMA/mana_ib : Send event to qp

I didn't look very deep into the series and has three very initial comments.
1. Please do git log drivers/infiniband/hw/mana/ and use same format for
commit messages.
2. Don't invent your own index-to-qp query mechanism in last patch and use
xarray.
3. Once you decided to export mana_gd_register_device, it hinted me that it is
time to move to auxbus infrastructure.

Thanks
