Description of problem:

After a link down / link up cicle the ethernet card loses the promisc state, 
ifconfig shows PROMISC, but the programs doesn't receive packets.  Unset and

01:17:06 EDT 2006 i686 athlon i386 GNU/Linux

Ethernet card:
Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)
How reproducible:

Steps to Reproduce:
1. start tcpdump
2. disconnect and connect the ethernet cable
3. start a rpl client in the network
4. tcpdump doesn't show the packets
5. restart tcpdump and it sees the packets
Actual results:

Loses promisc status.

Expected results:

Maintains promisc status

proposed patch

I will probably push this patch upstream since it should resolve your issue.  

I would like to test it out first, but don't have access to any hardware today.
 Would a test-build be helpful or would you like to try this patch yourself? 
If you would like a test-build let me know what ARCH you would like and I can
put one together.
Comment 2 Bruno A. Crespo 2006-11-28 14:16:32 EST
The machine that has the problem is a production server, please, give me two 
or three days to schedule a reboot.  Thanks.
Comment 3 Andy Gospodarek 2006-11-30 12:07:41 EST
I posted the patch from Comment #1 to netdev since it seemed fine to me.

Were you able to build a test kernel with the patch from Comment #4 and verify
that it resolved your issue?

This fix should be in 2.6.20.
