From 33ecfa8af9e36f80d6faf154f64e3d185dd55f5a Mon Sep 17 00:00:00 2001 From: Samer El-Haj-Mahmoud Date: Wed, 30 Sep 2015 01:06:57 +0000 Subject: [PATCH] MdeModulePkg: Add SMBIOS 3.0 support in NetLibGetSystemGuid. NetLibGetSystemGuid gets the UUID from SMBIOS table to use as the System GUID (in DHCP and other network use cases). This change adds support to get the UUID from either SMBIOS 2.x or 3.0, since SMBIOS 3.0 uses a different GUID in the System Configuration Table.
