State Reports the current state of the network interface (see
EFI_SIMPLE_NETWORK_STATE
below). When an
EFI_SIMPLE_NETWORK driver has initialized a network
interface, it is left in the EfiSimpleNetworkStopped state.
HwAddressSize The size, in bytes, of the network interface’s HW address.
MediaHeaderSize The size, in bytes, of the network interface’s media header.
