E.3.4.12 PXE_IFTYPE
The interface type is returned by the Get Initialization Information command and is used by the BC
DHCP protocol function. This field is also used for the low order 8-bits of the H/W type field in
ARP packets. The high order 8-bits of the H/W type field in ARP packets will always be set to
0x00 by the BC.
