Michael Brown	254fe6e00e	Split DHCP packet creation into two parts: creating the basic packet structure, and populating it with options. This should allow us to use the same basic options list for both DHCPDISCOVER and DHCPREQUEST, plus making it much easier to set the non-constant parameters (e.g. requested IP address) in request packets.	2006-07-19 12:12:45 +00:00
Michael Brown	6c01d3bb95	Fix creation of the htype field; the ll_proto field from which it is derived is a 16-bit big-endian field, but htype is only 8 bits wide.	2006-07-17 13:07:14 +00:00
Michael Brown	b24947f0c0	Add sketch code to reassemble a DHCP packet from our internal "everything is a DHCP option" data structures. We need this code in order to be able to return a DHCP packet to a PXE NBP which reflects options from our multiple sources (e.g. NVS and DHCP server). This is expensive, but necessary. Having paid this cost, we may as well try to use the same code to generate our DHCP request packets, since the process is similar.	2006-07-17 12:47:22 +00:00
Michael Brown	12da7ea475	Add (untested) code for parsing a received DHCP packet and constructing a DHCP options block from the contents.	2006-07-15 19:24:55 +00:00
