Log Message:
-----------
NetworkPkg/SnpDxe: Update SnpDxe SNP_DRIVER struct out of DMA-able memory.
CPB, DB, and CDB structs to use DMA-able memory.
Updates the overall SNP_DRIVER allocation to use AllocatePool() instead of
PciIo->AllocateBuffer(). This moves this struct out of DMA-able memory.
Allocates the PXE_CDB struct as a pointer instead, using
PciIo->AllocateBuffer() for DMA-able memory.
End result:
CPB, DB, and CDB are allocated with individual PciIo->AllocateBuffer() calls
with a size of 4096 for CPB and DB. and sizeof(PXE_CDB) for CDB.
Each of these members point to locations within the Allocated Buffer, and all
of these pointers are at-least
8-Byte aligned.
SNP_DRIVER is allocated with AllocatePool()
In the SNP_DRIVER structure, the PXE_CDB member is changed to a pointer so we
can allocate it with PciIo->AllocateBuffer()
