[Bridge] STP Explanation
Hi,
I'm trying to modify the stp kernel files in order to implements the RSTP. I've already modify the bpdu format like this :
------------------------------------------------------------------------------------------------------------------------------------
typedef struct
{
int topo_change = 0;
int proposal = 0;
int port_role[2] = {0,0} ; //role du port ?metteur du BPDU initialis? ? UNKNOWN
