Subject: [PATCH net-next 07/10] tg3: Use devfn to determine function number
Date: Sat, 5 Jun 2010 20:24:36 -0700 [thread overview]
Message-ID: <1275794679-11085-8-git-send-email-mcarlson@broadcom.com> (raw)
The driver sometimes needs to know which function number the current
device is. This patch changes the code to use devfn over internal
register values.
