From: Felix Fietkau Date: Thu, 19 Jan 2017 13:20:09 +0000 (+0100) Subject: MIPS: Lantiq: Keep ethernet enabled during boot X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=774f0c6419bb8f9d83901d33582c7fe3ba6a6cb3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git MIPS: Lantiq: Keep ethernet enabled during boot Disabling ethernet during reboot (only to enable it again when the ethernet driver attaches) can put the chip into a faulty state where it corrupts the header of all incoming packets. This happens if packets arrive during the time window where the core is disabled, and it can be easily reproduced by rebooting while sending a flood ping to the broadcast address.
