[f-nsp] Packet loss on MLXe-4

[Frank Bulk]

We didn't try other ports.  The IP video ingress of the ring was on the new
card, eth 2/1, and the inter-border router link was bad when moved to eth
2/2.

That card is the spare, so we can't pop another one in.

Could we theoretically swap the two cards around, as part of our
troubleshooting?

Not that Brocade is aware of. (I've asked the question to them)

Do you get the same packet loss on other ports on slot 2?  First blush 
would be a bad packet processor.  Do you have a spare you can drop in to 
test?
