eth: fbnic: support FW communication for core dump

Browse source

To read FW core dump we need to issue two commands to FW:
 - first get the FW core dump info
 - second read the dump chunk by chunk

Implement these two FW commands. Subsequent commits will use them
to expose FW dump via devlink heath.
