Stefan, I've got the test up and running now. Here's the interface config: 6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP link/ether 68:05:ca:2f:83:10 brd ff:ff:ff:ff:ff:ff inet 200.0.0.10/24 brd 200.0.0.255 scope global bond0 valid_lft forever preferred_lft forever inet6 fe80::6a05:caff:fe2f:8310/64 scope link valid_lft forever preferred_lft forever 9: p4p1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 9000 qdisc mq master bond0 state UP qlen 1000 link/ether 68:05:ca:2f:83:10 brd ff:ff:ff:ff:ff:ff inet6 fe80::6a05:caff:fe2f:8310/64 scope link valid_lft forever preferred_lft forever 12: p4p4: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 9000 qdisc mq master bond0 state UP qlen 1000 link/ether 68:05:ca:2f:83:10 brd ff:ff:ff:ff:ff:ff inet6 fe80::6a05:caff:fe2f:8310/64 scope link valid_lft forever preferred_lft forever p4p1 and p4p4 are the i40e interfaces bonded to the bond0 LACP interface. Here's the traffic results from a transmitter: Interim result: 9899.84 10^6bits/s over 5.001 seconds ending at 1439847706.406 Interim result: 9900.15 10^6bits/s over 5.001 seconds ending at 1439847711.407 I have a script watching the dropped packets for the two slaved interfaces p4p1 and p4p4: Every 1.0s: ./t1 Mon Aug 17 14:43:31 2015 rx_dropped: 0 tx_dropped: 0 rx_fcoe_dropped: 0 port.rx_dropped: 0 port.tx_dropped_link_down: 0 rx_dropped: 0 tx_dropped: 0 rx_fcoe_dropped: 0 port.rx_dropped: 0 port.tx_dropped_link_down: 0 I'll let this run overnight and get back to you with results tomorrow.
