It is not true, see "Port Transmit state machine": the function txRstp()
is called when & only when the condition 
endRSTP && newInfo && (txCount < TxHoldCount) && (helloWhen !=0)
It means, that, for example, if a Port plays Designated role, it realy
sends BPDU every hello-time. But if the port is unlinked, its role is
Disables, isn't it?
