[PATCH RFC v2 for-next 0/7] ib core support to send ib port link event

[Weihang Li <liweihang@huawei.com>]

From: Lang Cheng <chenglang@huawei.com>

Some provider driver has realized this function, but these code are
implemented separately by each manufacturer. This series provides an
solution in ib_core, and remove the relevant codes of some manufacturers.

The key point is how to shield the port event of the backup port in the ib
bonding scenario. Since the active-backup control is judged by the vendor
driver, so the ops.query_port of vendor would determine the port role. And
there is no relevant data structure in ib_core, so modify struct
ib_port_cache to store this information.

Supports reporting port active time during device registration and sending
port error events when device is deregistered.

The previous discussion can be found at:

Changes since v1:
- Fix comments from Leon and Jason.

- Move event processing flow into global notifier instead of one notifier
  per device.

Lang Cheng (7):
  RDMA/core: add inactive attribute of ib_port_cache
  RDMA/mlx5: remove deliver net device event
  qede: remove invalid notify operation
  RDMA/qedr: remove deliver net device event
  RDMA/vmw_pvrdma: remove deliver net device event
  RDMA/core: support send port event
  RDMA/core: report link status when register and deregister ib device
