Ping rate is unlimited for any kernel version. At least, I see 15kpps with zero packet loss and rtt below 100usecs. Taking into account that "ping -f" does not buffer output, it is close to perfect. It is the first.
And the second: Dick, you were said already dozen of times: 1. your ping is buggy. Upgrade. 2. nothing occured in 2.1, it was behaviour of Linux since 1.0 or so.
Please, stop to confuse people.
