tcp: change type of alive from int to bool
The alive parameter of tcp_orphan_retries, indicates whether the connection is assumed alive or not. In the function and all places calling it is used as a boolean value. Therefore this changes the type of alive to bool in the function definition and all calling locations. Since tcp_orphan_tries is a tcp_timer.c local function no change in any other file or header is necessary. Signed-off-by: Richard Sailer <richard@weltraumpflege.org> Signed-off-by: David S.
