From 209740fd132e48cd1ed31abd720d362f48074606 Mon Sep 17 00:00:00 2001 From: Felix Riemann Date: Tue, 18 Oct 2022 12:47:54 +0200 Subject: [PATCH] net: phy: dp83822: disable MDI crossover status change interrupt [ Upstream commit 7f378c03aa4952507521174fb0da7b24a9ad0be6 ] If the cable is disconnected the PHY seems to toggle between MDI and MDI-X modes. With the MDI crossover status interrupt active this causes roughly 10 interrupts per second. As the crossover status isn't checked by the driver, the interrupt can be disabled to reduce the interrupt load.
