From: Helin Zhang Date: Tue, 24 May 2016 06:22:58 +0000 (+0800) Subject: net/i40e/base: limit PF/VF specific code to that driver only X-Git-Tag: spdx-start~6516 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2db70574247b97b542165de809ce580b3366c5e3;p=dpdk.git net/i40e/base: limit PF/VF specific code to that driver only This patch trims the source code, with limiting pieces of code for PF or VF driver only, code style fixes, and annotation rewording.
