Subject: [PATCH 01/02] misc-net-drivers: Use ARRAY_SIZE macro when appropriate

From: "Ahmed S. Darwish" <[email-masked]>
Date: Mon, 5 Feb 2007 18:56:57 +0200

Hi,

A 2.6.20 patch to use ARRAY_SIZE macro already defined in kernel.h for some
miscellaneous network drivers with no specific maintaners.

Signed-off-by: Ahmed S. Darwish <[email-masked]>
---
[PATCH 01/02] is compile tested.
[PATCH 02/02] isn't compile tested cause of missing hardware.
