[v2,1/2] ethdev: add symmetric toeplitz hash support
Checks
Commit Message
From: Simei Su <simei.su@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.
