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

Add support for FW crash detection and a corresponding delink 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

Jakub Kicinski (9):
  eth: fbnic: make fbnic_fw_log_write() parameter const
  eth: fbnic: use fw uptime to detect fw crashes
  eth: fbnic: factor out clearing the action TCAM
  eth: fbnic: reprogram TCAMs after FW crash
  eth: fbnic: support allocating FW completions with extra space
  eth: fbnic: support FW communication for core dump
  eth: fbnic: add FW health reporter
  eth: fbnic: report FW uptime in health diagnose
  eth: fbnic: add OTP health reporter
