Subject: [PATCH net-next v3 0/9] eth: fbnic: add devlink health support for FW crashes and OTP mem corruptions

Add support for FW crash detection and a corresponding devlink health
reporter. Add a reporter for checking OTP memory health.

The output is not particularly exciting:

  # devlink  health show
  pci/0000:01:00.0:
    reporter fw
      state healthy error 0 recover 0 auto_dump true
    reporter otp
      state healthy error 0 recover 0 auto_dump true
  # devlink health diagnose pci/0000:01:00.0 reporter fw
   FW uptime: 0
  # devlink health dump show pci/0000:01:00.0 reporter fw
   FW coredump:
      5a 45 01 00 04 00 06 00 00 00 00 00 4d 01 00 d0 
      .. lots of hex follows ..
  # devlink health dump show pci/0000:01:00.0 reporter otp
   OTP:
     Status: 0 Data: 0 ECC: 0

v3:
 - [patch 2] add parsing policies
 - [patch 7] use extack
 - [patch 8] split time in diagnose callback into sec and msec
 - [patch 8] don't report when netdevice is down
v2: https://lore.kernel.org/20250915155312.1083292-1-kuba@kernel.org
 - [patch 2] fix attr ID
 - [patch 2] comment and commit msg adjustments
v1: https://lore.kernel.org/20250912201428.566190-1-kuba@kernel.org
