Ack, wasn't sending this back to the list.
No such luck for me on disabling the kernel config directives:
# cat /boot/config-`uname -r` | grep -i vlan
CONFIG_BRIDGE_EBT_VLAN=m
CONFIG_VLAN_8021Q=n
CONFIG_VLAN_8021Q_GVRP=n
CONFIG_MACVLAN=m
CONFIG_R8169_VLAN=y
After a reboot, and still a no go. I've seen some things around about
the ixgbe drivers not properly disabling vlan tag stripping in some of
the older versions, I wonder if the pf_ring_aware driver was built on
one of those versions. Doesn't make sense why ethtool isn't able to
modify the offload settings, though.

We had same issue with our application, until we unloaded kernel module
it didnt work.
Perhaps it is different in your case. From: Garrett, Ryan

No VLAN module loaded:
# rmmod 8021q
ERROR: Module 8021q does not exist in /proc/modules
Maybe I should try adding it.
Thanks

Try unloading vlan module, solved issue for us. From: Ryan

Subject: [Ntop-misc] Using PF_RING Aware Drivers with VLAN Trunk I'm
running into an interesting issue, and I was curious if anyone else
has ran into it.
I can run the DNA drivers and be able to pull traffic into
Snort/TCPDUMP without an issue, but if I try to run the PF_RING Aware
Drivers for my ixgbe card I get no traffic. I'm pretty sure it is to
do with VLAN tagging, I just haven't been able to figure out what
exactly. I've tried using ethtool to disable 'rxvlan' but it isn't
able to make the changes.
Has anyone else ran into this? I really don't want to have to make a
tagged interface for each VLAN, and the DNA drivers won't work for us
since we'll be pushing out to multiple IDS applications, and only one
application can exist on a queue, although I may just be
misunderstanding how the DNA drivers work.
Here's some output from ethtool:

Anyone have any ideas on this?
