Description Veaceslav Falico 2010-09-26 15:02:22 UTC
Description of problem:
In an active/backup bonding network interface with vlans on top of it, when a link fails over, it takes a minute for the multicast domain to be rejoined. 

Version-Release number of selected component (if applicable):
2.6.9-89.EL

How reproducible:


Steps to Reproduce:
1. Create bonding a/b, attach a vlan on top of it
2. Simulate the failover
3. There are no IGMP join packets sent
  
Actual results:
No IGMP join packets sent


Expected results:
The driver sends IGMP join.
