Subject: [PATCH 04/14] Conditionally enable transparent flow flag when connecting
Date: Saturday, October 13, 2007 - 1:31 pm

Set FLOWI_FLAG_ANYSRC in flowi->flags if the socket has the
transparent socket option set. This way we selectively enable certain
connections with non-local source addresses to be routed.
