This patch eliminate special cases by adding a fast_handler member to the receive context and changes to the fast handler as specified in the new variable. Initialize the variable as soon as the setting for dma tail is known when the context is created. Setting fast path is called every time when any context has entered slow path. Add function to check if contexts is using fast path and do not set fast path when it is already done to improve RCD fastpath setting.
