Eldon,

Our Brocade reseller is aware of the issue you're describing and says it's
being worked on.  He's asking what code release you're on and if it's 10G or
40G specific.

Frank

I have seen other strange things on the ICX7750, the most concerning
of which is a temporary forwarding loop on an MCT LAG during every
boot.

The code still seems a bit immature...
