Route function in the network module

[Lobo-T]

This isn't really a problem, I'm just curious.

I have made a board with an RP2350, a RM2 module and a Wiznet850io module.
I have compiled my own firmware with the W5500 driver. MicroPython v1.27.0-preview.293.g8995a291e0.dirty on 2025-10-09
Everything seems to work.

But I noticed there is a route() function in the network module:

>>> help(network)
object <module 'network'> is of type module
  __name__ -- network
  country -- <function>
  hostname -- <function>
  ipconfig -- <function>
  route -- <function>
  WLAN -- <class 'CYW43'>
  STAT_IDLE -- 0
  STAT_CONNECTING -- 1
  STAT_WRONG_PASSWORD -- -3
  STAT_NO_AP_FOUND -- -2
  STAT_CONNECT_FAIL -- -1
  STAT_GOT_IP -- 3
  WIZNET5K -- <class 'WIZNET5K'>
  STA_IF -- 0
  AP_IF -- 1

I could not find any documentation of this function.
I got curious if setting a routing table was actually possible, and tried to find the implementation of this function.
And it seems it pretty much only lists the network interfaces. Fair enough I wasn't really expecting anything.

But...
After connecting to both the CYW43 interface and the WIZNET5K interface it appears to only print the wiznet interface:

>>> network.route()
[<WIZNET5K>]

Is this a bug, or?

You may need to dig into the MicroPython source code to find these answers :)
