From 14807449a4a04fa478c5aba2142b6c157cfcfe4b Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 16 Nov 2020 18:02:30 +0100 Subject: [PATCH] net: e1000: Add missing address translations Add some missing address translations from virtual address in local DRAM to physical address, which is needed for the DMA transactions to work correctly. This issue was detected while testing the e1000 driver on the MIPS Octeon III platform, which needs address translation.
