From 0941036f4206d74bfc3d3e505a5d269fb39c48ff Mon Sep 17 00:00:00 2001
From: mansijos <mansi.joshi@intel.com>
Date: Tue, 6 Apr 2021 02:12:56 +0530
Subject: [PATCH] Entity-manager: Add support to update assetTag
Asset tag is an updateable property from User level interface like
Redfish. User-level interface will update Asset tag in entity-manager,
which will further update the needed FRU interface property exposed.
Tested:
Successfully updated in assetTag interface as well as in fru interface
while using set-property and using redfish as well.
The new value is preserved after BMC resets.
