From 8d92e4fbcf0fb7ecb24223b7b1ce95b9beb4dfa2 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Mon, 25 Apr 2022 06:44:21 +0300 Subject: devlink: introduce line card devices support Line card can contain one or more devices that makes sense to make visible to the user. For example, this can be a gearbox with flash memory, which could be updated. Provide the driver possibility to attach such devices to a line card and expose those to user. Example: $ devlink lc show pci/0000:01:00.0 lc 8 pci/0000:01:00.0: lc 8 state active type 16x100G supported_types: 16x100G devices: device 0 device 1 device 2 device 3 Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.
