From 3c18cbe33711d7f46aa3787c79ff809011f54b40 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 27 Jun 2019 23:12:39 +0200 Subject: [PATCH] r8169: consider that 32 Bit DMA is the default Documentation/DMA-API-HOWTO.txt states: By default, the kernel assumes that your device can address 32-bits of DMA addressing. For a 64-bit capable device, this needs to be increased, and for a device with limitations, it needs to be decreased. Therefore we don't need the 32 Bit DMA fallback configuration and can remove it.
