* udhcp: add PXELINUX path prefix option (code 210) definitionJeremy Kerr2014-07-161-0/+2
| | | | | | | | | | | | | | | Like d3092c99, this change adds support for the DHCP "path-prefix" option, as defined in RFC 5071. We use the string identifer "pxepathprefix". Adding this option makes string parsing in the hook scripts simpler. function old new delta dhcp_option_strings 255 269 +14 dhcp_optflags 72 74 +2 Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* udhcp: add PXELINUX config file option (code 209) definitionJeremy Kerr2013-11-121-0/+2
| | | | | | | | | This change adds a definition for DHCP option 209. RFC 5071 defines code 209 as a configuration file for a PXE bootloader; this change uses the string "pxeconffile" as its text identifier.
