+== HW28: MAC Address ETH1 GW53xx/GW54xx
+Issue:
+ * The MAC address of ETH1 is programmed the same as ETH0(MAC0). Thus, duplicate MAC's exist on both ETH interfaces. 
+ * Note, it is very rare this would be encountered. It would require to have both ethernet ports plugged into identical network segments. This is a specialized case. Even in a case where a failover is being used, everything would still work as the failover port wouldn't be active until the primary port fails. Performing things like bonding or assigning a port to a virtual server are scenarios where this errata may affect the system.
+
+Work-around:
+ * Manually set the ETH1 to MAC1 at runtime each time the board boots with the following script:
+  * 
+{{{
+# Obtain the 2nd MAC address from the Gateworks System Controller EEPROM
+mac1=$(i2cdump -f -y 0 0x51 | grep "00: " | cut -c 23-39 | tr " | " ":")
+# set the address
+ip link set dev eth1 down
+ip link set dev eth1 address $mac1
+ip link set dev eth1 up
+ip link show eth1
+}}}
+ * Return the SBC to Gateworks via an RMA to have the board reprogrammed.
