imx8mp eqos & sja1105p vlan filter issue

Hi, nxp term. Our custom board architecture consists of an imx8mp-evk and an sja1105P switch chip. The imx8mp's eqos network card is connected to the third port of the switch as the host, and the other four sub-ports are connected to four devices. Each device sends L2 layer data packets. I'm now adding VLAN port isolation to isolate the four sub-ports from each other, but adding VLANs causes the following kernel error.

Hi,

Thank you for your interest in NXP Semiconductor products,

Can you share your setup schematics? I don't understand the setup with i.MX 8MP EVK and SJA1105 switch.

Share your BSP version, please.

Also, share the results of switch ports network activity without VLAN, are ports active?

Regards
