[PATCH rdma-next v3 0/7] Support RDMA events monitoring through

[Michael Guralnik <michaelgur@nvidia.com>]

This series consists of multiple parts that collectively offer a method
to monitor RDMA events from userspace.
Using netlink, users will be able to monitor their IB device events and
changes such as device register, device unregister and netdev
attachment.

The first 2 patches contain fixes in mlx5 lag code that are required for
accurate event reporting in case of a lag bond.

Patch #3 initializes phys_port_cnt early in device probe to allow the
IB-to-netdev mapping API to work properly.

Patches #4,#5 modify and export IB-to-netdev mapping API, making it accessible
to all vendors who wish to rely on it for associating their IB device with
a netdevice.

Patches #6,#7 add the netlink support for reporting IB device events to
userspace.

Changes in v3:
	- Fix lockdep warning in ib_device_get_netdev by dropping
	  optimization part from it
	- Extend event info to include device names
	- Instead of disregarding unknown events, report them to
	  userspace
	- Remove fill_mon_register and replace with fill_nldev_handle to
	  fill netlink messages for register events

Changes in v2:
	- Fix compilation issues with forward declaration of ib_device
	- Add missing setting of return code in error flow

Chiara Meiohas (5):
  RDMA/mlx5: Initialize phys_port_cnt earlier in RDMA device creation
  RDMA/device: Remove optimization in ib_device_get_netdev()
  RDMA/mlx5: Use IB set_netdev and get_netdev functions
  RDMA/nldev: Add support for RDMA monitoring
  RDMA/nldev: Expose whether RDMA monitoring is supported

Mark Bloch (2):
  RDMA/mlx5: Check RoCE LAG status before getting netdev
  RDMA/mlx5: Obtain upper net device only when needed
