Can't set hostname in AP mode

[LucaDevelop]

Board: Raspberry Pico W
Firmware file name: rp2-pico-w-20220713-unstable-v1.19.1-129-g5bf376563.uf2

I can't set the "hostname" param with config() function.

This works (without hostname param):

import network
wlan = network.WLAN(network.AP_IF)
wlan.config(essid='somessid', key="1234567890")
wlan.active(True)

This doesn't work:

import network
wlan = network.WLAN(network.AP_IF)
wlan.config(essid='somessid', key="1234567890", hostname="somehostname")
wlan.active(True)

and prints this error:

Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
ValueError: unknown config param

I've tried with "dhcp_hostname" also, same result.

This is not currently supported on pyboard-d and pico-w (they use the same wifi driver).

It's not terribly complicated to add as the underlying driver already supports it. extmod/network_cyw43 needs to have the hostname parameter added to config, then it needs to not use the hard coded value in

and

I'd like to send this in, if no one is currently working on it, along with some proposed changes to connect.

Although this was merged in CYW43: Allow setting hostname. by iabdalkader · Pull Request #8918 · micropython/micropython, it doesn't seem to have made it into the rp2-pico-w-20220808-unstable-v1.19.1-241-g6baeded32.uf2 nightly

@iabdalkader:
Trying to build the binaries with MICROPY_PY_NETWORK_CYW43_USE_LIB_DRIVER=0 fails.
How did you succeed and test setting hostname?

See #10635

It seems the last time i found it was mentioned is that you should "dhcp_hostname" instead of "hostname" to set the hostname. I found it here and the concret link would be this.
I might be completly mistaken but from what i saw this should resolve the issue. I am eager to hear how it turned out for you. But from my point of view it seems the doc is not 100% correct on this.
