From: Felix Riemann Date: Tue, 18 Oct 2022 10:47:54 +0000 (+0200) Subject: net: phy: dp83822: disable MDI crossover status change interrupt X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7f378c03aa4952507521174fb0da7b24a9ad0be6;p=linux.git net: phy: dp83822: disable MDI crossover status change interrupt 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.
