Subject: [PATCH iwl-next v2] i40e: Add support for fw health report
Add support for reporting fw status via the devlink health report.
Example:
# devlink health show pci/0000:02:00.0 reporter fw
pci/0000:02:00.0:
reporter fw
state healthy error 0 recover 0
# devlink health diagnose pci/0000:02:00.0 reporter fw
Mode: normal
Signed-off-by: Kamal Heib <kheib@...hat.com>
---
v2:
- Address comments from Jiri.
- Move the creation of the health report.
