Subject: [PATCH net-next 15/15] bnxt_en: Add support for devlink info command
From: Vasundhara Volam <vasundhara-v.volam@...adcom.com>
Display the following information via devlink info command:
- Driver name
- Board id
- Broad revision
- Board Serial number
- Board Package version
- FW version
- FW management version
- FW RoCE version
Standard output example:
$ devlink dev info pci/0000:3b:00.0
pci/0000:3b:00.0:
driver bnxt_en
serial_number B0-26-28-FF-FE-25-84-20
versions:
fixed:
board.id C454
board.rev 1
running:
board.package N/A
fw.version 216.0.154.32004
fw.mgmt 864.0.0.0
fw.app 216.0.51.0
