Our device is a Jetson AGX Xavier with L4T version 35.2.1.
A KSZ9897 switch is plugged in.
The kernel driver used by KSZ9897 is Linux_for_Tegra\source\public\kernel\kernel-5.10\drivers\net\dsa\microchip: CONFIG_NET_DSA_MICROCHIP_KSZ9477_SPI.
KSZ9897 driver can be loaded normally, ifconfig can see one eth1 and five lanx.
eth and lan can ping each other after configuration.

sudo ip link set eth1 up
sudo ip link set lan1 up
sudo ip link set lan2 up
sudo ip link set lan3 up
sudo ip link set lan4 up
sudo ip link set lan5 up

sudo ip link add name br0 type bridge
sudo ip link set dev lan1 master br0
sudo ip link set dev lan2 master br0
sudo ip link set dev lan3 master br0
sudo ip link set dev lan4 master br0
sudo ip link set dev lan5 master br0

sudo ip addr add 172.31.0.150/24 dev br0
sudo ip link set dev br0 up

But when SSH connect, the kernel will report the following panic：

sorry, no experience with this switch. Please contact the vendor to check if this is known issue first.
