From eb65132adca3fe1e7c39fc6032266a8d04150561 Mon Sep 17 00:00:00 2001 From: Nico Erfurth Date: Sun, 27 Feb 2011 17:57:30 +0100 Subject: [PATCH 2/2] nameif: Added matching for PhyAddresses Very useful when trying to distinguish platform-devices served by the same driver, which is actually quite common in embedded-devices.
