Bug#503020: linux-image: tcp_dsack causes hangs when using proxy server

["Jonathan A. Zdziarski" <jonathan@zdziarski.com>]

maybe, but if that's the case, then there are a lot of broken gateways  
or filters out there... is it really healthy to make tcp_dsack on by  
default? I know it was meant to be backward compatible but it doesn't  
look like it turned out that way; seems like it'd be more of an  
optimization than a default.
