We have some preliminary perf data that doesn't look great,
but we hope to improve it :)

On a LS2088A with A72 cores @2GHz (numbers in Mpps):
				1core		8cores
-------------------------------------------------------------------------
XDP_DROP (no touching data)	5.68		29.6 (linerate)
XDP_DROP (xdp1 sample)	3.46		25.18
XDP_TX(xdp2 sample)		1.71		13.26

For comparison, plain IP forwarding through the stack
is currently around 0.5Mpps (1c) / 3.8Mpps (8c).

Currently supported LS2088A, LS1088A, soon LX2160A (all with
ARM64 cores).

I should have an answer for this early next week and will
get back to you.

Thanks,
Ioana
