Subject: [dpdk-dev] [PATCH v7 3/4] i40e: support of controlling hash functions
Date: Fri, 28 Nov 2014 20:14:11 +0800
Message-ID: <1417176852-12345-4-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1417176852-12345-1-git-send-email-helin.zhang@intel.com>

Hash filter control has been implemented for i40e. It includes
getting/setting,
- global hash configurations (hash function type, and symmetric
  hash enable per flow type)
- symmetric hash enable per port

v5 changes:
* Integrated with filter API defined recently.

v6 changes:
* Implemented the mapping function to convert RSS offload types to
  Packet Classification Types, to isolate the real hardware
  specific things.
* Removed initialization of global registers in i40e PMD, as global
  registers shouldn't be initialized per port.
* Added more annotations to get code more understandable.
* Corrected annotation format for documenation.

v7 changes:
* Remove swap configurations, as it is not allowed by hardware design.
* Put symmetric hash per flow type and hash function type into
  'RTE_ETH_HASH_FILTER_GLOBAL_CONFIG', as they are controlling global
  registers which will affects all the ports of the same NIC.
