Subject: [dpdk-dev] [PATCH v3 5/7] i40e: add hardware initialization
Date: Tue, 30 Sep 2014 14:20:26 +0800
Message-ID: <1412058028-10971-6-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1412058028-10971-1-git-send-email-helin.zhang@intel.com>

As global registers will be reset only after a whole chip reset,
those registers might not be in an initial state after each
launching a physical port. The hardware initialization is added
to put specific global registers into an initial state.

v3 changes:
* Renamed hardware initialization function.
* Added initialization of register 'PFQF_CTL_0'.
