I use netconn APIs.
I found it always create tcp pcb with TCP_PRIO_NORMAL.
i.e. the priority is all the same.

So in such case, killing the active connections with the same priority
or not does matter.
In current code, create new connection won't fail because it will
always kill the oldest active connections.
Such behavior seems strange because I would expect new connection to
fail rather than killing existing active connections.
