rx_align_err in Testpmd

Hello dear,

I would like to understand why I have rx_align_err counter increasing in my DPDK testpmd application.

I have one LS1043 board running pktgen connected to a LS1046 board over the 10G copper port running testpmd. I'm using LSDK 19.09. The forwarding works good however when I print the xstats in testpmd I have the following :

After googling this type of issue it seems that it comes from CRC errors or odd bytes number.

I tried different setups (also with a lx2160 board) and different cables but the issue still remains.

Tanks for your help,

Etienne Cordroc'h
