[Kernel 5.15.68] encx24j600 device driver issue over SAMA5D2 MPU

[afinfante]

Dear community,
In the integration on my custom board that is stated in the title of this issue I am having problems with the driver of the same. The PMOD NIC100 is fully functional, but I have to perform a power cycle whenever I copy files using scp. Do you know what could be happening?

I have done some research on the internet but nothing remarkable.

P.D.: the interrupt I have assigned to it in the board dts is 35 (active low).
