The bonding method for adding VLAN Identifiers (VIDs) did not always add the VID to a slave VLAN group. When the NETIF_F_HW_VLAN_FILTER flag was not set on a slave, the bonding module could not add new VIDs to it. This could cause networking problems and the system to be unreachable even if NIC messages did not indicate any problems. This update changes the bond VID add path to always add a new VID to the slaves (if the VID does not exist). This ensures that networking problems no longer occur in this scenario.
Regression test is done , all the test are PASS.
The NIC we have tested:
The test items :
1. Connection test (all 7 bond modes)
Beaker job link in Comment 6
2. Jambo Frame test (mtu 9000)
3. tcp/udp/igmp/sctp (ipv4/ipv6) protocol test
In Comment 8 & https://beaker.engineering.redhat.com/jobs/262752
4. loop change active slave test (each slave)
change_active_slave task in https://beaker.engineering.redhat.com/jobs/262968
5. loop load/unload bonding and 8021q module test (100 times)
6. Bonding Tier1 Test (arp_monitor bond_bridge_dhcp bond_bridge_lro bond_dhcp module_load_unload)
