Function Documentation

void ixgbe_atr_compute_perfect_hash_82599	(	union ixgbe_atr_input *	input,
		union ixgbe_atr_input *	input_mask
	)

ixgbe_atr_compute_perfect_hash_82599 - Compute the perfect filter hash : input bitstream to compute the hash on : mask for the input bitstream

This function serves two main purposes. First it applys the input_mask to the atr_input resulting in a cleaned up atr_input data stream. Secondly it computes the hash and stores it in the bkt_hash field at the end of the input byte stream. This way it will be available for future use without needing to recompute the hash.
