Packet dequeuing

tcsim can dequeue (``send'') packets either automatically, based on the interface speed, or when explicitly requested with the poll command. If no rate is specified on an interface, it will only send packets if polled.

poll $[$device$]$
Tries to dequeue packets. If no packets are available, poll has no effect. If no device name is specified, poll polls all available devices.
