Definitely agree on the “understanding/defining the behaviors of a bridge”.
Most stacks seem to have a bridge concept that is at least defined in man
pages/online documentation, not sure I’ve seen the concept defined in an IEEE
document. We would have to define a set of features for a bridge in LwIP
Here’s an example for FreeBSD:
