LS1028 DPDK port status seems to be wrong

[Gourmet]

My board is LS1028 which has ETH ports for 1000Mbps, I verified it by iperf3.

However, when I tried  DPDK (which 1028 is supported), Something went wrong:

following the document, I first change the dtb with the DPDK one, then run the /dpdk_configure_1028ardb.sh. 

I started my DPDK test by:

./dpdk-testpmd -l 0-1 -n 4 -- -i --portmask=0x1 --nb-cores=1

logs here:

testpmd> 

(tried with --iova-mode=pa also, but nothing changed)

but my port status should be 1000Mbps with full duplex, what's going on?  Is there anything wrong with my configuration or hardware? 

Yours sincerely

By reading DPDK source code, 10Mbps and half duplex are the default case as the result of switch registers reading, when the reading result goes wrong, then 10M and half will be the status.
