Date: Tue, 28 Apr 2020 11:03:54 -0500 From: Dan Murphy <dmurphy@...com> To: <andrew@...n.ch>, <f.fainelli@...il.com>, <hkallweit1@...il.com> CC: <linux@...linux.org.uk>, <davem@...emloft.net>, <linux-kernel@...r.kernel.org>, <netdev@...r.kernel.org>, <afd@...com>, Dan Murphy <dmurphy@...com> Subject: [PATCH net v3 2/2] net: phy: DP83TC811: Fix WoL in config init to be disabled The WoL feature should be disabled when config_init is called and the feature should turned on or off when set_wol is called. In addition updated the calls to modify the registers to use the set_bit and clear_bit function calls.
