+=== Shared characteristics ===
+  * MIPS 4KEc 500MHz CPU
+  * SPI boot flash up to 32MB
+  * 8 gigabit embedded PHYs
+=== Differences ===
+  * The 8380M has an additional 8 PHYs connected via 2 QSGMII ports and 2 SGMII ports, for a total of 18 ports maximum.
+  * The 8382M has 4 QSGMII ports connected to two 8-port PHYs, for 24 ports maximum.
+  * The 8382L has no DDR RAM interface, making it less suited to managed switches.
