LS1043A-RGW Dev Board GigE interface speeds and Loss

[tmorrison]

Hi,

I am running on a LS1043A-RGW Development board - using the ASK

binaries that were provided. I have a Spirent Packet Generator/tester

that I am working with GigE LAN directly connected to Eth2 and Eth3

of the Dev. Board.

I then configure the networking rules on the LS1043A to route Spirent

data between eth2 and eth3 (basically direct bridge between the two

GigE ethernet ports).

Then, we turn on the Spirent to see what we see.

Below ~33% loading (~330Mbits) - we have little loss and within reason

Unfortunately, over that ~speed, we start getting packet loss and packet

re-ordering issues - and @ 1GigB - its about 8-9% errors and a lot

of packet re-ordering going on.

What are we doing wrong?

Tom

I should clarify because this explanation was very unclear.

Using an openwrt 19.07.03 version and running on the LS1043A-RGW

Development Board, I was getting lost, duplicate, and re-ordered packet

errors above 330Mbits/Second (we had FMAN code and uboot code

from ASK sent separately to our team).

Using untouched the LS1043A-RGW Development Board - I was able

to get full line-rate.

Is this the fact that the LS1043A requires the DPAA enabled to get

anywhere close to line speed.
