Selfmade patch for docsis_server 2.0.4, pair ipaddr CPE with customer CM

Yesterday I wrote patch for docsis_server 2.0.4. I add something like this: - You can pair ipaddr for customer with their modem. - Even if client has new macaddr for CPE he still get their own IPaddr with new mac addr. - You can pair more then one IP CPE with one modem_macaddr - in thise case new mac addr will get IP, which was granted earliest This patch need new table in docsis_server CREATE TABLE `dhcp_pair` ( `modem_macaddr` varchar(15) NOT NULL, `ipaddr` varchar(16) NOT NULL, `cmts_vlan` mediumint(9) NOT NULL, `time` timestamp NOT NULL default CURRENT_TIMESTAMP ) ENGINE=MyISAM DEFAULT CHARSET=latin1; it work like this: - when someone connect new CPE to CM docsis_server make a select from dhcp_leases, - if select from dhcp_leases get 0 rows then docsis_server make a select from dhcp_pair - if it find ipaddr related to modem_macaddr the docsis_server make insert ipaddr and cpe macaddr into dhcp_leases - in second ask of IP cpe will get correct IP. - if in dhcp_pair are not any pair then cpe will not get IP. - if in dhcp_leases exist ipaddr, but with different mac docsis_server will update new mac here is a patch: http://sloniewski.pl/public/docsis_server-2.0.4.patch Any hint what I can add? ps.
