Netif traffic indicator

[DrMickeyLauer]

My design uses a W5500 and the builtin WiFi to provide a bridge. I'd like to indicate the network traffic via one LED. In our hardware design, we didn't want to hardwire the signalling, hence my task is to do it in software. While I get events for link up and link down, I wonder where to hook best to build a custom IP_EVENT_TRAFFIC event that I can listen for in my higher layers.

Ok, I guess I found the relevant parts in components/esp_netif/lwip/esp_netif_lwip.c, esp_netif_transmit & esp_netif_receive. I'll patch those function to send events over the default event loop. I will test with ipperf to check whether this will lead to a performance degration or not.

Seems to be fine, so in case anyone else needs something like that, here's my pull request: https://github.com/espressif/esp-idf/pull/13348

Thanks for traffic reporting feature! With this, I'll try to implement traffic counters
But I cannot find it neither in IDF v5.2.2 nor in IDF v5.3.1.
Could you please remind me which IDF version has network traffic reporting?
I consider connecting my device thru GSM modem and I'd like to account incoming and outgoing internet traffic

I don't know. The PR has been merged back in April, so it's in master by now, but I don't know when they will backport it to the next release. Perhaps try asking on https://github.com/espressif/esp-idf/pull/13348

I made a netif traffic counter for GSM modem, but I needed to pull unstable esp-idf from master.
I guess it's needed an example for esp-idf to be able to add the traffic counter to future release.

Here are some logs from my GSM modem project which connects to Telegram bot:
