Hello,
The bug is in OVS. In my tests it was necessary change de following lines
in the ofproto/ofproto-dpif-xlate.c
<http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob;f=ofproto/ofproto-dpif-xlate.c;h=5dba2e678b0af196ec174ecdf9139d05df8c3766;hb=2ca476b8ae918f6db2af7c147ea0cb807a734939>.
This return to the old, but functional, implementation of the function
which performs the sending of the BPDUs in OVS.
