Hi Xiaoliang,

After enable multiple queues in dts by default, eqos can't boot with NFS, NFS can't be mounted at the end. Can this reproduce at your side?

Best Regards,
Joakim Zhang

Subject: [PATCH net-next 1/2] arm64: dts: imx8mp-evk: configure multiple
queues on eqos

Eqos ethernet support five queues on hardware, enable these queues and
configure the priority of each queue. Uses Strict Priority as scheduling
algorithms to ensure that the TSN function works.
