-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.
-
