commit 454911333b1d86e1d58a557be271bc6b7e9e7f10 upstream.
When port is put into LISTENING state it shouldn't populate the FDB, so set the port's STP state in hardware to DISCARDING instead of LEARNING. It will therefore keep listening to BPDU packets, but discard other non-control packets and won't perform any learning.
