From f15908aa036585a80016fa7c02421b6d293a7550 Mon Sep 17 00:00:00 2001 From: Chris Phillips Date: Tue, 10 Jan 2017 14:49:08 +0800 Subject: [PATCH] MdePkg: Add comments for SMBIOS Type 3 structure to cover SKU Number Starting with SMBIOS spec version 2.7, Type 3 added SKU Number. SKU Number is at a variable offset (depends on count and length of Contained Elements), so cannot add SKU Number to the SMBIOS_TABLE_TYPE3 structure. Adding comments to explain how to get SKU Number.
