From 9ab5c929e641c68ab3ade762b330e22e29c51f13 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 11 Jul 2018 21:32:42 +0200 Subject: [PATCH] net: gemini: Improve connection prints Switch over to using a module parameter and debug prints that can be controlled by this or ethtool like everyone else. Depromote all other prints to debug messages. The phy_print_status() was already in place, albeit never really used because the debuglevel hiding it had to be set up using ethtool.
