But looking at the code at br_stp_set_enabled() in br_stp_if.c it doesn't matter which value you echo into stp_state, it just have to be non-zero The detection of usermode oder kernelmode STP is done using the usermode helper (see br_stp_start). I tried echoing 1, 2 or even 5 into stp_state, with a working /sbin/bridge-stp I get 2 from stp_state each time. Maybe it is valuable to change this odd behavior.
