[dpdk-dev] [PATCH v2 1/2] ethdev: add symmetric toeplitz hash support

[simei]

From: Simei Su <simei.su at intel.com>

Currently, there are DEFAULT,TOEPLITZ and SIMPLE_XOR hash function.
To support symmetric hash by rte_flow RSS action, this patch adds
new hash function "Symmetric Toeplitz" which is supported by some hardware.
