Subject: [dpdk-dev] [PATCH v2 2/5] i40e: renaming and code style fix
Date: Sun, 14 Sep 2014 22:48:26 +0800
Message-ID: <1410706109-30448-3-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1410706109-30448-1-git-send-email-helin.zhang@intel.com>

Rename some local variables in i40e_pf.c and
i40e_ethdev_vf.c, to express more accurately and briefly.
Fix several issues in i40e_pf.c reported by checkpatch.pl.
Line warpping for some source lines which has more than 80
characters, and merge lines together for those source lines
which does not need any line wrapping actually.

v2 changes:
* Put all the renaming and code style fixes into a patch.
* Add several more code style fixes for i40e_pf.c.
