Add support for drop action for steering rules

Hi Doug,

This patch set introduces support for drop steering rule feature.

The application can configure a steering rule to drop all the packets that match this rule.

In order to create a drop steering rule, the user has to add the drop flow specification as part of the other flow specifications, otherwise the packet will be forwarded to the destination QP.

Thanks,
Slava and Leon.
