Hi, I have two questions: 1. br_designated_port_selection() in br_stp.c: In this function, the port, which is not DISABLED and br_should_become_designated_port, then the port is becoming designated port. Question: Why the port state(DISABLED) is checking here? According to standard, there should not be any checking for disabled. 2. br_stp_set_bridge_priority() in br_stp_if.c: In this function also, the same DISABLED checking is done. Question: Why the port state(DISABLED) is checking here also for updating the bridge priority? Thanks and Regards, Prasenjit
