#   [IPVS] update mark->cw in the WRR scheduler while service is updated
#   
#   It's for better performance in the WRR scheduling when server weight is adjusted.
#   The change is ported from the changes of IPVS in kernel 2.6. Thanks must go to
#   Kees Hoekzema <kees@xxxxxxxxxxxx> for finding the WRR problem in kernel 2.6.
