Hi All,

I can reproduce this bug easly with tap echo server (attached here), that I
was small reworked.

steps (almost same):
(All ip addresses/macs hardcoded in code).

On first machine run echo server, on second add

[EMAIL PROTECTED] route add -net 192.168.125.1/24 ip-addr-of-first-machine

and

[EMAIL PROTECTED] ping -f -n 192.168.125.2

While flood pinging, on first machine run ping for checking:

[EMAIL PROTECTED]  ping 192.168.125.2
PING 192.168.125.2 (192.168.125.2): 56 data bytes

64 bytes from 192.168.125.2: icmp_seq=1 ttl=64 time=0.180 ms
...
wait for a while
...
