Hm. Maybe this is bitrot. Please check that the first part of the patch got
applied and wasn't rejected. Specifically, line 65ish should be:
cid.fill(chassis_id.SUB_LOCAL, array.array('B', 'dpid:' + hex(long(dpid))
[2:-1]))
If it is, try replacing the log message around line 268 with something
slightly more useful:
lg.error("lldp chassis ID subtype is " + str(lldph.tlvs[0].subtype)
+ " not 'local', ignoring")
