[PATCH net-next v2] 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.
