From 74b4f1739d4e81810e1d20f0e6ad3d3c63a32c13 Mon Sep 17 00:00:00 2001 From: James Hershaw Date: Mon, 23 Jan 2023 14:41:35 +0100 Subject: [PATCH] nfp: flower: change get/set_eeprom logic and enable for flower reps The changes in this patch are as follows: - Alter the logic of get/set_eeprom functions to use the helper function nfp_app_from_netdev() which handles differentiating between an nfp_net and a nfp_repr. This allows us to get an agnostic backpointer to the pdev. - Enable the various eeprom commands by adding the 'get_eeprom_len', 'get_eeprom', 'set_eeprom' callbacks to the nfp_port_ethtool_ops struct. This allows the eeprom commands to work on representor interfaces, similar to a previous patch which added it to the vnics. Currently these are being used to configure persistent MAC addresses for the physical ports on the nfp.
