SnpDxe is the Simple Network Protocol DXE driver implementing EFI_SIMPLE_NETWORK_PROTOCOL over an UNDI3.1 network interface. It provides the full SNP interface including transmit/receive, multicast filtering, station address management, statistics collection, and NVRAM data operations. The driver includes self-contained replacements for BaseMemoryLib operations with debug assertions, plus ASCII/Unicode string conversion and linked-list utilities compiled directly into the module.
