+Subject: [PATCH] dropbear server: support -T max auth tries
+
+Add support for '-T n' for a run-time specification for maximum number
+of authentication attempts where 'n' is between 1 and compile time
+option MAX_AUTH_TRIES.
+
+A default number of tries can be specified at compile time using
+'DEFAULT_AUTH_TRIES' which itself defaults to MAX_AUTH_TRIES for
+backwards compatibility.
