DnsDxe, Index 0144, 52004 bytes, DXE Phase

UEFI DNS Protocol DXE driver for the AMI network stack. Implements EFI_DNS4_PROTOCOL and EFI_DNS6_PROTOCOL for DNS resolution (A/AAAA record queries) over UDP4/UDP6. Maintains per-service DNS caches with timer-based aging, manages retry/timeout logic, and supports known RR type validation.

Key Functions

• ModuleEntryPoint -- DXE entry, installs DNS4 and DNS6 driver binding protocols
• Dns4DriverBindingSupported/Start/Stop -- IPv4 DNS driver binding
• Dns6DriverBindingSupported/Start/Stop -- IPv6 DNS driver binding
• DnsCreateService/DnsDestroyService -- DNS service binding lifecycle
• Dns4GetHostByName/Dns4GetHostByAddress -- IPv4 name resolution
• Dns6GetHostByName/Dns6GetHostByAddress -- IPv6 name resolution
• DnsTimerNotify -- Periodic cache aging (1-second interval)

Protocols/Dependencies

• EFI_DNS4_PROTOCOL, EFI_DNS6_PROTOCOL
• EFI_UDP4_PROTOCOL, EFI_UDP6_PROTOCOL
• EFI_DPC_PROTOCOL
• AMI Debug Library Protocol
