Tue 26 May 2020 11:49:49 AM UTC, comment #1: Indeed, that can be troublesome for systems with multiple netifs as we do not have separate Rx pools for interfaces, starving the Rx pool for garbage is not a really nice behavior. For single netif system that should not be an annoying problem since the worse that can happen is a failure to allocate the single PBUF needed for PPPoS Tx when PPPoS Rx is currently filling the last Rx PBUF, hoping it does not happen at a noticeable rate.

Today I had an issue with the wifi module I use where it crashes and resets, dropping its baud rate in the process and dumping a whole lot of rubbish on the serial port. This is received as a long series of 0x80, 0x80, 0x80, x80, ... due to the baud rate mismatch.

I agree that should be a good candidate, it is not that bad in the wild but the fix is harmless. The branch does not seem to be updated that often, or at least, not day to day, I have no clue if Simon keep a list somewhere or if he just cherry-pick what seem to be fixes when he want to do a release.
