dpaa2 dpsw port report dpsw_cnt_ing_no_buffer_discard: xxxx error

i want to forwarding udp traffic to vpp via  dpsw port on lx2160a board.

when i generate  1.2Gps udp traffic to dpsw port .
we find the max_rate that dpsw can reach is only 900Mps,

use restool we find dpsw report dpsw_cnt_ing_no_buffer_discard:22262XXX

the dpsw configuration as below:

ls-addsw  -s=32768 -i=4 dpmac.15 dpni.1 dpmac.5 dpni.5
soc:LX2160a
kernel:4.19.90

MC firmware version: 10.38.1

we don't know how to fix it .

The port speed is 10Gbps.
I checked the guide you referred to, but I couldn't find the solution.
Could you please advise on how to resolve this?

Best regards

Hello,

The DPAA2 architecture and its DPSW component are designed to handle high-speed traffic,
but the actual speed will be that of the physical port being used, which can be 1 Gbps,
10 Gbps, 25 Gbps or even higher, depending on the SoC (System-on-Chip) specifications
and configuration.
