From: Mintz, Yuval Date: Thu, 6 Apr 2017 12:58:31 +0000 (+0300) Subject: qed: Don't close the OUT_EN during init X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd1cc771f9d2374f9f1c0edbd01d27893723e8da;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git qed: Don't close the OUT_EN during init Before initializing the chip's engine, driver currently closes a set of registers on the HW's ingress flow to prevent packets from slipping in while they're not supposed to. This configuration is insufficient, as there are some scenarios where packets would still arrive even when said registers are set, but the management firmware already closes other per-port registers that do suffice, making this setting unnecessray.
