Michael Brown	2df682c5be	[dhcp] Allow DHCP non-option settings to be cleared dhcppkt_store() is supposed to clear the setting if passed NULL for the setting data. In the case of fixed-location fields (e.g. client IP address), this requires setting the content of the field to all-zeros.	2008-07-08 01:13:59 +01:00
Michael Brown	7a4e212fe2	[DHCP] Treat empty fields in DHCP packets as non-existent. This avoids confusing other code by insisting that we have e.g. a filename consisting of 128 zero bytes.	2008-03-27 06:06:36 +00:00
Michael Brown	92d15eff30	[Settings] Remove assumption that all settings have DHCP tag values Allow for settings to be described by something other than a DHCP option tag if desirable. Currently used only for the MAC address setting. Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c. Remove notion of settings from dhcppkt.c. Rationalise dhcp.c to use settings API only for final registration of the DHCP options, rather than using {store,fetch}_setting throughout.	2008-03-25 20:46:16 +00:00
