Subject: [RFC PATCH iproute2-next V2] System specification exception API

The exception spec is targeted for Real Time Alerting, in order to know when
something bad had happened to a PCI device
- Provide alert debug information
- Self healing
- If problem needs vendor support, provide a way to gather all needed debugging
  information.

The exception mechanism contains condition checkers which sense for malfunction. Upon a condition hit,
actions such as logs and correction can be taken.

The condition checkers are divided into the following groups
- Hardware - a checker which is triggered by the device due to
  malfunction.
- Software - a checker which is triggered by the software due to
  malfunction.
Both groups of condition checkers can be triggered due to error event or due to a periodic check.

Actions are the way to handle those events. Action can be in one of the
following groups:
- Dump -  SW trace, SW dump, HW trace, HW dump
- Reset - Surgical correction (e.g. modify Q, flush Q, reset of device, etc)
Actions can be performed by SW or HW.

User is allowed to enable or disable condition checkers and its action mapping.

This RFC man page patch describes the suggested API of devlink-exception in order
to control conditions and actions.

V2:
* Renaming terms:
	health -> exception
	sensor -> condition
* Remove reinit command and merge with action command.
* Consmetics in grammer.
