[dpdk-users] bonding - slave mac address is not updated

[Eugene Iskra]

Hello,

I am using DPDK 18.11.2 with bonding in BONDING_MODE_ACTIVE_BACKUP mode.
When both slaves are connected to the switch, the primary slave receives 
/ sends traffic
and everything work well.
When the primary port is disconnected, and the secondary slave becomes 
primary,
no packets are received, except for broadcast packets.

Looking at bond_ethdev_lsc_event_callback in rte_eth_bond_pmd.c, I see that
mac_address_slaves_update is called only when slave link is brought up, 
but if slave
goes down, mac addresses are not updated.

Also the mac_address_slaves_update function itself doesn't seem to 
update mac address
correctly for the new primary port, since it updates 
internals->primary_port instead
of internals->current_primary_port.

Is this an actual bug or am I misunderstanding something / something is 
not configured
right?


Regards,
Eugene
