ASUS GT-AC5400


 * • 4800 Mbps - 8SS 5GHz 802.11ac (80MHz chan.),
 * • 600 Mbps - 4SS 2.4GHz 802.11n (40MHz chan.) = AC5400 class

A Declaration of Model Names document at the FCC states that this
 * ASUS GT-AC5400 is identical except for its lack of the 10G copper
 * (RJ45) port found in the ASUS GT-AX6000.

A note in the user manual says, "The SFP+ interface only operates at
 * a 10Gbps speed and is not compatible with a 1 Gigabit data rate."
