lacp: warn transmit failure of lacp pdu
It might be difficult to trace whether LACP PDU tx (as in response) was successful when the pdu was not transmitted by egress slave for various reasons (including resource contention within NIC) and only way to trace its fate is by looking at ofproto->stats.tx_[packets/bytes] and slave port stats. Adding a warning when there is tx failure could help user debug at the root of this problem. Signed-off-by: Gowrishankar Muthukrishnan <gmuthukr@redhat.com> Signed-off-by: Ben Pfaff <blp@ovn.org>
