Re: tcp_tick

RTT is stored in ticks of the TCP clock, not in seconds; tcp_tick stores
the value in seconds of the lenght of each tick (note that by default is 
100ms instead the standard 500ms of the Tahoe source), so that

RTT [in seconds] = RTT [in ticks] * tcp_tick_

Or directly in TCL,

set rtt_sec [expr [$tcp set rtt_] * [$tcp set tcpTick_]]
