ip: rate-limit the sending of ICMP error messages
Type: improvement
For error conditions, such as TTL expired, dest unreach, etc, Rate limit the sending of ICMP error messages.
The rate limiting is done based on src,dst IP address of the received packet.
the rate limit has been chosen, somewhat arbitrarily, to be 1e-3. This is the same limit as the ARP throttling.
