Description Michel Machado 2024-04-29 20:11:08 CEST 
The bonding driver does not receive all packets in 8023ad mode (LACP) when it has two or more members. This bug happens because the bonding driver does not add the bond's MAC address to the members, so only the member whose MAC address is the same as the bond receives packets. One can verify the bug by calling rte_eth_macaddrs_get() on the members after the bond is started.

There are two workarounds:

1. Putting the bond in promiscuous mode with rte_eth_promiscuous_enable(), so all members receive all packets.

2. Obtaining the MAC address of the bond _after_ adding all members with rte_eth_macaddr_get(), _and_ adding this MAC address to all members with rte_eth_dev_mac_addr_add().
