Bridge device itself only has one MAC address. > Are you trying to run macvlan on top of bridge? > We only respond to ARP with bridge's MAC address. host1 uses a bridge with two interfaces: ethernet and wireless (AP mode using hostapd) for some reasons, hostapd kept adding and removing the interface from the bridge, triggering a mac address of the bridge change each time (I did not notice that). Another host had a static arp entry for host1, using the ethernet mac address, so its packets to host1 were randomly trashed depending on the current mac of the bridge. I have since fixed this by setting a static mac address on the bridge to prevent dynamic change, but I thought this patch would prevent other people from having the same bug in the future.
