From d6956ac87b5ff6841b09c273a70de86200d82019 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Wed, 29 Mar 2017 16:47:19 +0800 Subject: [PATCH] net: mvneta: set rx mode during resume if interface is running I found a bug by: 0. boot and start dhcp client 1. echo mem > /sys/power/state 2. resume back immediately 3. don't touch dhcp client to renew the lease 4. ping the gateway. No acks Usually, after step2, the DHCP lease isn't expired, so in theory we should resume all back. But in fact, it doesn't. It turns out the rx mode isn't resumed correctly. This patch fixes it by adding mvneta_set_rx_mode(dev) in the resume hook if interface is running. Signed-off-by: Jisheng Zhang Reviewed-by: Andrew Lunn Signed-off-by: David S.
