-	 * We need to check to see what to do about buffer sizes here.
-	 * - In an HPN to non-HPN connection we want to limit the window size to
-	 *   something reasonable in case the far side has the large window bug.
-	 * - In an HPN to HPN connection we want to use the max window size but
-	 *   allow the user to override it.
-	 * - Lastly if HPN is disabled then use the ssh standard window size.
-	 *
-	 * We cannot just do a getsockopt() here and set the ssh window to that
-	 * as in case of autotuning of socket buffers the window would get stuck
-	 * at the initial buffer size, generally less than 96k.  Therefore we
-	 * need to set the maximum ssh window size to the maximum HPN buffer
-	 * size unless the user has set TcpRcvBufPoll to no.  In that case we
-	 * can just set the window to the minimum of HPN buffer size and TCP
-	 * receive buffer size.
