ls1043ardb bridge performance

Hi,

I tried to make simple bridging between fm1-mac2 and fm1-mac5 gigabit ports. I used this comand

flex-installer -i auto -m ls1043ardb -d /dev/mmcblk0 -r rootfs_lsdk2108_ubuntu_main_arm64.tgz

to generate SD card image. After succesfull boot from SD card and login i run this commands:

ip addr add 192.168.3.80/24 dev fm1-mac1
ip route add default via 192.168.3.1

ip link add br0 type bridge
brctl setfd br0 0 #at to jede rovnou
ip link set fm1-mac2 master br0
ip link set fm1-mac5 master br0
ip link set fm1-mac6 master br0
ip link set up dev br0
ip link set up dev fm1-mac2
ip link set up dev fm1-mac5
ip link set up dev fm1-mac6
sysctl net.bridge.bridge-nf-call-iptables=0

to set up ip access on port fm1-mac1 and bridge between fm1-mac2,5,6.

Then I measured bidirectional performance via smartbits SMB200 gigabit cards RFC-1242 & RFC-2544 between fm1-mac2 and fm1-mac5 ports.

This is my results:


Frame Size	Passed Rate(%)	(01,01,01) to (01,03,01) (pks/sec)	(01,03,01) to (01,01,01) (pks/sec)	Total
		1GB -1GB	1GB -1GB
64	7,98	118821	118821	237642
128	8,01	67641	67641	135282
256	10,99	49761	49761	99522
512	59,11	138889	138889	277778
1518	71,94	58466	58466	116932

Is it normal, that for 64B and 128B frame size is throughput only 80MBitsps?

Can I achieve full 1Gbit performance somehow (using DPAA/DPDK)?

Is somewhere some simple example how to set it up on this board? I tried to read some manuals about DPAA/DPDK, but I am not understand it much.

Is possible to configure fm1-macX ports like L2 switch without need much CPU power?

Thanks.

Some suggestions about this test:
1. try to generate multiple-flows and make sure the multi-flows are spread across multi-cores. You can double confirm it through checking CPU usage "mpstat 1 -P ALL", or checking DPAA interrupts on each core.
2. disable netfilter if iptable/ebtable is not used (CONFIG_NETFILTER=n)
