└─>Marvell Armada 38x/XP network interface BM support
In linux kernel since version 4.1 (release Date: 2015-06-21)  
This driver supports auxiliary block of the network
interface units in the Marvell ARMADA XP and ARMADA 38x SoC
family, which is called buffer manager.

This driver, when enabled, strictly cooperates with mvneta
driver and is common for all network ports of the devices,
even for Armada 370 SoC, which doesn't support hardware
buffer management.
