Hi. I read the bridge code of linux kernel. But now I meet a puzzle. In file net/bridge/br_stp_if.c line 157 Void br_stp_recalculate_bridge_id() {
. List_for_each_entry(p, &br->port_list, list) { If (addr==br_mac_zeor || Memcmp(p->dev->dev_addr, addr, ETH_ALEN) <0) //why to find the min of all macs???? Add = p->dev->dev_addr; }
}
Who can answer my question? Thanks very much!!!!
BR, Echo
