[PATCH v2 2/2] net: have checksum routines accept unaligned data

__rte_raw_cksum() (used by rte_raw_cksum() among others) accessed its data through an uint16_t pointer, which allowed the compiler to assume the data was 16-bit aligned. This in turn would, with certain architectures and compiler flag combinations, result in code with SIMD load or store instruction
