[ovs-dev] [PATCH net-next v2 0/2] ovs: introduce arch-specific fast hashing improvements

[Francesco Fusco]

From: Daniel Borkmann <dborkman at redhat.com>

We are introducing a fast hash function (see patch1) that can be
used in the context of OpenVSwitch to reduce the hashing footprint
(patch2). For details, please see individual patches!

Thanks !

v1->v2:
 - Make hash generic and place it under lib

  lib: introduce arch optimized hash library
  net: ovs: use CRC32 accelerated flow hash if available
