Subject: [PATCH 5/5] bridge: minor cleanups

From: Stephen Hemminger <[email-masked]>
Date: Fri, 22 Jul 2011 10:47:10 -0700

Some minor cleanups that won't impact code:
  1. Remove inline from non-critical functions; compiler will most
     likely inline them anyway.
  2. Make function args const where possible.
  3. Whitespace cleanup
