Subject: [dpdk-dev] [PATCH v3 09/24] net/i40e/base: add link speed convert function
Date: Tue, 9 Jan 2018 15:30:07 -0500 [thread overview]
Message-ID: <1515529822-10732-10-git-send-email-qi.z.zhang@intel.com> (raw)
In-Reply-To: <1515529822-10732-1-git-send-email-qi.z.zhang@intel.com>
Introduce a helper function which can convert the AdminQ link speed
definition into a virtchnl definition. This can then be used by host
driver implementations in order to safely convert to the interface
recognized by the virtual functions.
