Bug ID: 238580
Summary: [PATCH] respect defines from 'sys/netinet/ip_carp.h'
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: egyp...@freebsd.org

D20638.diff
based on information from man pages like carp(4) and ifconfig(8), some
inconstant values popped out while I troubleshooted a HA setup using CARP.
- advskew was able to be changed to values higher than CARP_MAXSKEW;
- CARP advertisements collected via tcpdump were still using (respecting) its
limit;
changing values on net.inet.carp.demotion does not increase advskew above the
limit (expected, I think).
