Message-ID: <alpine.LFD.2.11.1404080022120.26128@eddie.linux-mips.org>
Date: Tue, 8 Apr 2014 13:19:28 +0100 (BST)
From: "Maciej W. Rozycki" <macro@...ux-mips.org>

Subject: [PATCH 1/2] FDDI: Reformat <linux/if_fddi.h> for 8-character tabs
Some of our FDDI support code has been apparently written with an
assumption that tabs are 4-character wide. In preparation to the next
change this update reformats <linux/if_fddi.h> so that it stays within 79
columns and otherwise renders correctly with 8-character tabs. No
functional change.
