ICMP error messages that exceeded the value are subject to rate limitation
and will not go out from the node.
Negative value disables rate limitation.
.It Li icmp.rediraccept
If set to non-zero, the host will accept ICMP redirect packets.
Note that routers will never accept ICMP redirect packets,
and the variable is meaningful on IP hosts only.
.It Li icmp.redirtimeout
The variable specifies lifetime of routing entries generated by incoming
ICMP redirect. This defaults to zero; if the system is not running
a routing daemon like
.Xr routed 8
than this value can be set to remove the routes added by redirect.
A reasonable value to use would be 600 seconds.
.It Li tcp.rfc1323
Returns 1 if RFC1323 extensions to TCP are enabled.
