Re: [dpdk-users] error running bonding example - Rx offloads capabilities 0x0 in rte_eth_dev_configure()

[Alex Zelichenko <alex@scadafence.com>]

Hi Cliff,
Can you help me with the second part of the issue? How do I get the packets
from bonded interface into my tcpdump-like application? Is that interface
(net_bonding0) accessible from outside the application that created it?
Best,
Alex Z
