The change is to enable PcdsDynamicHii in Duet platform. Duet's variable driver should run at TPL <= TPL_CALLBACK so Pcd Dxe driver should run at TPL <= TPL_CALLBACK.

2) Change ARCHITECTURAL_PROTOCOL_ENTRY name to EFI_CORE_PROTOCOL_NOTIFY_ENTRY so it can be used for both Architectural Protocols and optional protocols that the DXE Core may use. Also remove BOOLEAN ArchitecturalProtocol field, so it is back to its original form.
3) Put mArchProtocols[] back to its original form, but add a NULL entry at the end so the end of the table can be easily detected in loops
4) Add mOptionalProtocols[] that at this time only has the SMM Base 2 Protocol in it.
5) Add NULL entry to mMissingProtocols[] so the end of the table can be easily detected.
6) Update all loops on mArchProtocols[], mOptionalProtocols, and mMissingProtocols[] to remove Index(s) and simply looks for a NULL ProtocolGuid to find the end of the table.
7) Update protocol notify events to pass the associated EFI_CORE_PROTOCOL_NOTIFY_ENTRY * as the Context parameter. This simplifies GenericProtocolNotify() by completely eliminating the search loop.

PI 1.2 SMM Drivers are allowed to call UEFI/DXE services and Protocols from the entry point of the PI 1.2 SMM Driver. These UEFI/DXE services and Protocols may directly or indirectly calls the UEFI Boot Services RaiseTPL() and RestoreTPL(). These UEFI Boot Services use the CPU Architectural Protocol to enable interrupts if the TPL level is below TPL_HIGH_LEVEL and enable interrupts of the TPL is at TPL_HIGH_LEVEL. Interrupts should be masked while executing SMM drivers, so if a direct or indirect call to the UEFI Boot Service RestoreTPL() would enable interrupts, then an interrupt could be incorrectly delivered in SMM context.
The solution is for the DXE Core to register for the PI 1.2 SMM Base2 Protocol. If that protocol is present in the platform, then the DXE Core can use the SMM Base 2 Protocol's InSmm() function to determine if the platform is currently executing in SMM content. If the current context is in SMM, then do not allow any requests to be forwarded to the CPU Architecture Protocol to enable interrupts.

This would not normally cause an issue because the correct notification function was being called. There is only an issue if the same notification function is being used for multiple tokens, and the notification function needs to use the TokenNumber parameter to determine which token setting caused the callback function to be called.
Update the logic so the CallbackOnSet notification functions are not called with the internal PCD database lock in the acquired state. This allows other PCD Get/Set operations to be performed from within a CallbackOnSet notification.
Update logic so the PCD database lock is not left in the acquired state when SetWorker() returns EFI_INVALID_PARAMETER.

1. Reserve the unique string identifier for all languages in the package list.
2. Track MaxStringId to do the simple check for the requested StringId > MaxStringId, which can improve performance.

1. add library function NetLibDetectMedia to NetLib for media detection
2. update MnpDxe to periodically poll for media status update and check for media status before packet transmit
3. update Ip4Dxe to return ModeData using Mnp->GetModeData()
4. update IScsiDxe to check for media status before try to do DHCP and session login
5. update UefiPxeBcDxe to check for media status before PXE start
