net: Improve simple_tx_hash(). Based upon feedback from Eric Dumazet and Andi Kleen. Cure several deficiencies in simple_tx_hash() by using jhash + reciprocol multiply. 1) Eliminates expensive modulus operation. 2) Makes hash less attackable by using random seed. 3) Eliminates endianness hash distribution issues.
