Subject: [V2 patch] ShellPkg/SmbiosView: Update SmbiosView for SMBIOS3.2.0
Date: Tue, 28 Aug 2018 14:26:30 +0800	[thread overview]
Message-ID: <20180828062630.40172-1-dandan.bi@intel.com> (raw)

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1099

Update SmbiosView to parse the new definitions which
are introduced in SMBIOS3.2.0

V2:
1. Add structure length check before dump the fileds in
Type 9 and Type 17 in case some fileds are not organized
and reported by drivers.
2. Dump the InterfaceTypeSpecificData in Type 42.
