Hi Minoru, I hate to do this to you after i made suggestions on how to make the changes.... (as an adult i hate it when people do it to me;->) But sometimes code helps. So what i meant is the attached patch. I havent even compiled it yet. If it works, please submit it and add yourself as the author (and a signed-off from me). Then we can revisit the init() issue in cls_group.. You should also cc tgraf in your cls_grp config questions. cheers, jamal On Fri, 2009-05-29 at 09:46 -0400, jamal wrote: > > This is incorrect. tp may already exist and you dont want to destroy > for failure to change its parameters.
