What 'dirty tactics' was Vettel alluding to?

A lot of people tried to play dirty tricks but we did not get distracted by that and kept going our way and all the guys gave a big push right to the end

I'm not sure if he is just referring to the Massa gearbox one (which is perfectly fine imo) or anything else?

Thoughts? Was there more going on behind the scenes I wonder with rules changes, FIA and so forth.

Horner has mentioned it again - http://www.autosport.com/news/report.php/id/104641 - but still isn't specific.
