From c272ef4403c271799a7f09a4ab7a236c86643843 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Fri, 9 Nov 2007 16:56:25 -0600 Subject: ssb: Convert to use of the new SPROM structure In disagreement with the SPROM specs, revision 3 devices appear to have moved the MAC address. Change ssb to handle the revision 4 SPROM, which is a different size. This change in size is handled by adding a new variable to the ssb_sprom struct and using it whenever possible. For those routines that do not have access to this structure, a 'u16 size' argument is added. The new PCI_ID for the BCM4328 is also added. Testing of the Revision 4 SPROM, which is used on the BCM4328, was done by Michael Gerdau . Signed-off-by: Larry Finger Signed-off-by: John W.
