Running examples/protocols/http_server/simple with wiki defaults does not respond to requests

Hi all.
I am thankful that with 86ba82e I was able to run the hello-world example, however I'm still not able to make use of the ethernet examples, even though I'm following the wiki

Here is my qemu output:
output.txt

My sdkconfig:
sdkconfig.txt

My commands:
idf.py menuconfig (manually edited latter, removed WiFi, which also threw a panic)
idf.py build
./makeflash-img.sh simple simple.bin
/opt/esp-idf/qemu/xtensa-softmmu/qemu-system-xtensa -nographic -machine esp32 -drive file=simple.bin,if=mtd,format=raw -nic user,model=open_eth

Looking at the command line, you are using the user-mode networking (-nic user). User-mode networking in QEMU doesn't support IGMP protocol, so ping will not work.
And if the server is running on the ESP32, you need to explicitly tell QEMU that you would like to forward the port (hostfwd=tcp...). Please check QEMU documentation (https://qemu.weilnetz.de/doc/qemu-doc.html#Network-options) and the wiki (https://wiki.qemu.org/Documentation/Networking#User_Networking_.28SLIRP.29).

I just remembered what you said above about user-mode and ICMP, however the server is still not responding to get requests. Does it work on your end (on qemu)?

Also I fixed the error displayed by qemu on hw/net/opencores_eth.c, by changing line 61 MII_REG_MAX value to 17. (Max probably overlooked this).

59 /* PHY MII registers */
60 enum {
61 MII_REG_MAX = 17,
62 };

Still could not get the serve to reply at /hello.

Yes, it works on my with end with examples/protocols/http_server/simple and -nic user,model=open_eth,hostfwd=tcp::8082-:80 option to QEMU, then curl http://localhost:8082.

Thanks, was missing the hostfwd=tcp::8082-:80, I thought It would be directly accessible through the qemu machine.
