An idea: comment this line in ping_prepare_echo function:

iecho->chksum = inet_chksum(iecho, len);

All

I ported ping thread from contrib. packet, and found that it fails to works when IP, UDP, TCP and ICMP checksums by HW.

But it works when those checksums by SW.

 

Anyone meets same problem ?

 

Regards,

Vincent
