[settings] Add the notion of a "tag magic" to numbered settings

2008-10-30T21:47:14+00:00

Settings can be constructed using a dotted-decimal notation, to allow for access to unnamed settings. The default interpretation is as a DHCP option number (with encapsulated options represented as ".". In several contexts (e.g. SMBIOS, Phantom CLP), it is useful to interpret the dotted-decimal notation as referring to non-DHCP options. In this case, it becomes necessary for these contexts to ignore standard DHCP options, otherwise we end up trying to, for example, retrieve the boot filename from SMBIOS. Allow settings blocks to specify a "tag magic". When dotted-decimal notation is used to construct a setting, the tag magic value of the originating settings block will be ORed in to the tag number. Store/fetch methods can then check for the magic number before interpreting arbitrarily-numbered settings.

[Settings] Remove assumption that all settings have DHCP tag values

2008-03-25T20:46:16+00:00

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.

[Settings] Migrate DHCP and NVO code to the new settings API (untested)
