LACP+VLAN with 10G NIC not working

[Carles Guadall]

I configured a lacp (lagg0) with two 10G-Intel NICs. Latter I created 2 VLAN over lagg0.

When trying to ping from host vlan to any other hosts doesn't work. 
I ran tcpdump on each interface, ix[0|1], lagg0 and vlan[52|908].

- On each physical interface I see packets coming from network. I can see mainly broadcasts, correctly tagged, etc.
- On lagg0 interface I also see packets coming from network. When running tcpdump on vlanXX I only can see ARP requests from localhost.

It's seems packets doesn't "flow" from/to vnic and lagg.

Inbound 
( network ) --> [ix0] --> [lagg0] ---X---> [vlan52]
( network ) --> [ix0] --> [lagg0] ---X---> [vlan52]

Outbound 

( network ) <-- [ix0] <-- [lagg0] <---X--- [vlan52]
( network ) <-- [ix0] <-- [lagg0] <---X--- [vlan52]

Any idea what's wrong??
