On switch connect send LLDPs only from that switch. (https://github.com/floodlight/floodlight/pull/19)

Still had problems when switches with same DPID connect. Should be fixed now. (https://github.com/floodlight/floodlight/pull/20)

After a switch is asynchronously removed due to another switch with the
same DPID connecting, the first switch might still have messages qeued.
If we process these messages after removing the switch switch listeners
can get confused.

[#23382219]

Added *.class

Fix when switches with same DPIDs connect. (https://github.com/floodlight/floodlight/pull/18)

When a switch with an already existing DPID connects, close the
connection from the previously connected switch.
