From bd1cc771f9d2374f9f1c0edbd01d27893723e8da Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" <Yuval.Mintz@cavium.com> Date: Thu, 6 Apr 2017 15:58:31 +0300 Subject: [PATCH] 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.
