Description David Milburn 2005-08-03 16:08:09 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc3 Firefox/1.0.6

Description of problem:
When heaviliy sending UDP packets, the bonding driver failed to switch to the backup link.

http://marc.theaimsgroup.com/?l=bonding-devel&m=112056134412688&w=2

The problem is as follows.
1. While executing an application that transmits UDP packets
2. When the e1000 driver's link goes down
3. The bonding driver switches the link to the backup link, but no packets are sent from the new link.



Version-Release number of selected component (if applicable):
kernel-2.6.9-11.EL

How reproducible:
Sometimes

Steps to Reproduce:
1. Transmitt packets.
2. Cause e1000 driver's link to go down.
3. After that, the bonding driver will switch the link to the backup link.

  

Actual Results:  No packets are sent from the new link.

Expected Results:  The packets should be sent from the new link.
