From 460578bfe4dffbdc6eec9fcbd0fe0bb4f9f82188 Mon Sep 17 00:00:00 2001 From: Jay Cliburn Date: Sat, 2 Feb 2008 19:50:09 -0600 Subject: [PATCH] atl1: use netif_msg Use netif_msg_* for console messages emitted by the driver. Add a parameter to allow control of messaging at driver startup, and also add the ability to control it with ethtool.
