Subject: [net-next 4/9] i40e: split i40e_get_strings() into smaller functions
Date: Tue, 22 May 2018 10:45:22 -0700	[thread overview]
Message-ID: <20180522174527.19680-5-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20180522174527.19680-1-jeffrey.t.kirsher@intel.com>

From: Jacob Keller <jacob.e.keller@intel.com>

Split the statistic strings and private flags strings into their own
separate functions to aid code readability.
