I tested this "bug" with different kernels > 2.0.x, this is my report:

- ping -l 65510 linux_box (2.0.4) from Win95 , no problem , system log:
Kernel:ICMP failed ckecksum from Win95_box
- ping l 65510 linux_box (2.0.7/2.0.23) from Win95 - no services avaible
more, I can't connect (no telnet, no ftp, no ping), my monitor goes crazy
with a mega list of Hex numbers.
