Ok, I ran this for a lot longer and it seems less consistent than it did 
at first. It now appears that there is no correlation between a NIC not 
working and its order. In some cases the NICs both come up ok, and see 
traffic for a while. I left one example running over the weekend, and 
neither interface on one card was seeing traffic, and the interface 
counters weren't increasing. In another case, one interface on one NIC 
worked for a short period of time, then stopped. The interface counters 
would increase by a few packets every 30 seconds or so. Any kind of 
ethtool operation (e.g., ethtool -A eth4 autoneg off rx off tx off) 
would cause the interface to start seeing traffic again, then eventually 
go back to seeing only a few packets every few seconds.
