Device: GL-MT3000
Firmware: 4.6.3 (beta I think?)
OpenWrt Version:
OpenWrt 21.02-SNAPSHOT r15812+899-46b6ee7ffc

Hi there, hope I'm not crashing a thread with too much off-topicness, but couldn't help but sign up just to add to this cause I feel it's gotta be meaningful in some way and too much to be coincidence.

However, about an hour ago I started getting dropped from my video call I was on for work (Google meet and I was presenting my screen as well if that matters), now that's not too uncommon, I usually have to relogin to the captive portal as I'm at a hotel temporarily.

What was uncommon though was after reconnecting, I dropped again about 5 minutes later and couldn't reconnect no matter what i tried. Used cell phone Hotspot to connect the laptop back into the meeting, officially ended that, then jumped back to getting wifi reconnected.

Once reconnected finally went through the logs and saw something I never saw and that was multiple lines with

I decided to Google for "tx_free_v3_notify_handler()" as I thought that was unique enough to warrant the best results, and this is why I had to reply to this...

Googling that term which seems to be a method of a class of some sort, provided me with 3 results total. Now I've been googling in a support capacity for 20 years and when the top result is a forum thread from 2 days ago, that tells me this is extremely narrow in scope.

The 3rd result, coincidentally, is a forum post from here and it outlines an issue a user was having specifically when on video calls and being dropped. Coincidence? Not sure I can be convinced not.

I'd really really love to know what this tx_free_v3_notify_handler() is and what it's purpose is, as it seems to be exclusive to gl.inet firmware/software.
