Description of problem:
dnsmasq lacks the ra-param option
Version-Release number of selected component (if applicable):
Name : dnsmasq
Arch : x86_64
Version : 2.66
Release : 14.el7_2.1
The version of dnsmasq in RHEL7 lacks the ra-param option available in version 2.67 and above - which means that dnsmasq can't be used as a full replacement for radvd.
The particular use case here is when routers switch over and you want to lower the route priority/lifetime of one vs. the other.
