** Description changed: == SRU Justification == - The mvpp2 is a driver for network controllers(s) in Marvell SOCs, particularly Armada 8040. + The mvpp2 is a driver for network controllers(s) in Marvell SOCs, + particularly Armada 8040.

Could it be added, please, and the installer image re-generated.
