I doubt you'd get more than 300-500 megabit/s of large packets using 
regular Linux kernel forwarding on that platform.

This is with VPP or similar. In my tests Marvell 8040 platform will do ~4 
gigabit/s of Linux kernel forwarding (unidirectional and large packets) 
since all packets are handled by a single CPU core.

I am using WRT1200AC (Marvell armada 385 based) which is one of the best 
devices I have been able to find for running for instance OpenWrt and 
doing gig speeds with AQM. If you don't need AQM, then MT7621 based 
devices now have hardware flowoffload in OpenWrt 18.06 which means it'll 
do 1 gig unidirectional (unfortunately most of the hardware seems to be 
single gig port towards the SoC so you never get more than in+out=1 gig.
