Hallo
when i disable all lines in net/bridge/br.c which are related to following
lines:
static struct llc_sap *br_stp_sap;
..
br_stp_sap = llc_sap_open(LLC_SAP_BSPAN, br_stp_rcv);
if (!br_stp_sap) {
printk(KERN_ERR "bridge: can't register sap for STP\n");
return -EADDRINUSE;
}
...
Will i get as result that all stp packets are passed untouched other the
bridge ?
With regards,
Roman Glebov
