Link aggregation using LACP

[Naresh]

Hi All,

I am working on a 10Gb Ethernet driver for FreeBsd 8.2. When I enable link aggregation using LACP mode on two ports of our card, I expected load to be balanced on two ports(both are up). But interestingly traffic is flowing on only one interface. 

If I administratively bring down the interface on which traffic is flowing, I see lot of packet loss for about 30 secs, After that it picks up.

I think this is not expected. Are there any known issues with FreeBsd 8.2 ?

Thanks,
Naresh.
