Subject: [dpdk-dev] [PATCH v2 14/33] i40e/base: enhancements of NVM checksum calculation
Date: Thu, 30 Apr 2015 23:03:20 +0800 [thread overview]
Message-ID: <1430406219-23901-15-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1430406219-23901-1-git-send-email-helin.zhang@intel.com>
The data buffer for i40e_calc_nvm_checksum() is too big, so move
it off and allocate separately. In addition, use
i40e_read_nvm_buffer() to get the whole shadow RAM, together with
minor enhancements.
