[edk2-devel] [PATCH] ShellPkg:Improved Smbios Type 9 table changes in PrintInfo.c

[Sainadh Nagolu via groups.io]

Since PeerGroups has a variable number of entries, new fields added after PeerGroups are defined in a extended structure. Done changes in PrintInfo.c to access those fields using SMBIOS_TABLE_TYPE9_EXTENDED structure from SmBios.h.
