[PATCH rdma-next] RDMA/uapi: Fix and re-organize the usage of rdma_driver_id

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yishai Hadas <yishaih@xxxxxxxxxxxx>

Fix 'enum rdma_driver_id' to preserve other driver values before that
RDMA_DRIVER_CXGB3 was deleted.  As this value is UAPI we can't affect
other values as of a deletion of one driver id.

In addition,
- Expose 'enum rdma_driver_id' to user applications by moving it to
  ib_user_ioctl_verbs.h which is exposed in rdma-core to applications.

- Drop the dependency of ib_user_ioctl_verbs.h on ib_user_verbs.h which
  is not really required.

Fixes: 30e0f6cf5acb ("RDMA/iw_cxgb3: Remove the iw_cxgb3 module from kernel")
