Subject: [PATCH net-next 0/6] eth: fbnic: Add firmware logging support

Firmware running on fbnic generates device logs. These logs contain useful
information about the device which may or may not be related to the host.
Logs are stored in a ring buffer and accessible through DebugFS.

Lee Trager (6):
  eth: fbnic: Fix incorrect minimum firmware version
  eth: fbnic: Use FIELD_PREP to generate minimum firmware version
  eth: fbnic: Create ring buffer for firmware logs
  eth: fbnic: Add mailbox support for firmware logs
  eth: fbnic: Enable firmware logging
  eth: fbnic: Create fw_log file in DebugFS
