Subject: [dpdk-dev] [PATCH 11/15] i40e: expose debug_write_register request
Date: Tue,  9 Sep 2014 15:21:35 +0800
Message-ID: <1410247299-4365-12-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1410247299-4365-1-git-send-email-helin.zhang@intel.com>

The firware api request of writes to hardware registers should be
exposed to driver. The new API of 'i40e_aq_debug_write_register'
is introduced for that.
