Am I missing something about how MAC's are assigned to T2080RDB ETH4 and ETH5?

In Linux:

ifconfig fm1-mac3 192.168.0.22

ifconfig

fm1-mac3 Link encap:Ethernet  HWaddr 00:04:9f:03:c9:8c

Connected to ETH4 on front panel

Label on this port on T2080RDB has last # of MAC as 8D (Port next to USB stack).

Is there a chance the board is simply mislabeled with the MAC stickers?

Is this table correct regarding assignment of front panel ports to u-boot/Linux?

I have two RDB's doing this same thing.

From the QS guide, it appears ETH4 and ETH5 are swapped to front panel.

Here are our MAC labels (note routing to front panel.  Eth4 is going ot ETH5 front panel

A closer view:

Our front panel as assigned by actual MAC's

And a followup question:

Are ETH4 and ETH5 the only ports on this board that can run at 1Gbps?  Can Eth0, Eth1, Eth2, or Eth3 be configured to run at 1Gbps instead of 10Gbps, or does the PHY clock dictate that they are always at 10?
