Wiznet W5100S-EVB-Pico

MicroPython version

MicroPython v1.25.0 on 2025-04-15; W5100S-EVB-Pico with RP2040
also 1.24.1, and 1.24.0, but 1.23.0 doesn't give the error

Reproduction

MicroPython v1.25.0 on 2025-04-15; W5100S-EVB-Pico with RP2040

Type "help()" for more information.

import network
nic = network.WIZNET5K()
nic.ifconfig()
('192.168.1.137', '255.255.255.0', '192.168.1.254', '192.168.1.254')
nic.active(True)
wiznet5k_send_ethernet: fatal error -5
nic.isconnected()
True

Expected behaviour

Expected no error to be reported.
However, the error does not seem to affect the operation. The ethernet socket behaviour seems to be working ok.

Observed behaviour

wiznet5k_send_ethernet: fatal error -5
was printed out, but operation of ethernet seems to be working, however I can't be certain all functions are working correctly at this time

Additional Information
