udhcp: add PXELINUX path prefix option (code 210) definition
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>
