From 7ad506fa1adc2da3d394c562f09b8e1b3026c402 Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Fri, 26 Feb 2010 14:04:40 +0000 Subject: pci: Add large and small resource data type code This patch introduces more VPD preprocessor definitions to identify some small and large resource data type item names. The patch then continues to correct how the tg3 and bnx2 drivers search for the "read-only data" large resource data type.
