Packets delivered to an application via the accelerated path are not visible to the OS kernel. As a result, diagnostic tools such as tcpdump and wireshark do not capture accelerated packets. The supplied onload_tcpdump application does support capture of UDP and TCP packets from Onload stacks - Refer to onload_tcpdump for details.
