Pravin,
I am you hoping you can take a look at a potential problem with my kernel
module patch submitted to net-dev today. I decided to submit it anyway
because that is the best way to get eyes on it.
I am still seeing a problem where the 4 conntrak attributes show up in an
upcall when a double tagged packet is received. The attribute lengths for
the 4 unknown attributes should be -1 but are showing up as odd lengths. I
can't see where my patch below is causing this problem but I don't see
similar errors with missed upcall in either single tagged or untagged
packets. I have applied my companion patch to the user space for 802.1ad so
the problem could be in that patch with de-serializing "unknown" attributes.
Also, this may not be a problem at all because the kernel module includes
the conntrak patches but the user space does not as yet.
I am running ovs commit ca92d173 with my user space 802.1ad patch.
The error message is below:

I am not sure. can you send me github link to user-space patch, so
that I can check.
Pravin,
OK, also I noticed that the user space patch for conntrak was submitted
on 9/17. I think I will try to rebase user space patch on top of
conntrak patch and re-test after fixing issues in kernel patch.
Thanks,
