Hi, Maybe someone already has asked. The only official Linux bridge document I got is a very ancient wiki page[1] or the ip link man page[2][3]. As there are many bridge stp/vlan/multicast paramegers. Should we add a detailed kernel document about each parameter? The parameter showed in ip link page seems a little brief. I'd like to help do this work. But apparently neither my English nor my understanding of the code is good enough. Anyway, if you want, I can help write a draft version first and you (bridge maintainers) keep working on this.
