Adaptive Load Balancing "Mode 6" Packet loss

Hello,

My current setup is two 1GB connections to two separate switches (eth0 & eth1). LACP bonding is not an option due to switch VSS capabilities.

I have Mode 6 enabled and everything bonds, however I have almost 50% packet loss. I have experimented with MII and updown delay values with no success.

Has anyone experienced this type of issue with these alternate bonding modes?
