Description
The

network adapter has been initialized, the
allow packets to be transmitted and received. This provides a packet level interface that can then be
used by higher level drivers to produce boot services like DHCP, TFTP, and MTFTP. In addition,
this protocol can be used as a building block in a full UDP and TCP/IP implementation that can
produce a wide variety of application level network interfaces. See the Preboot Execution
Environment (PXE) Specification for more information.
