From 9aa17df3b84bc6df37398f51e8df6ed8e91049d4 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Wed, 11 Jul 2018 17:42:40 +0200 Subject: [PATCH] s390/qeth: fine-tune RX modesetting Changing a device's address lists (or its promisc mode) already triggers an RX modeset, there's no need to do it manually from the L2 driver's ndo_vlan_rx_kill_vid() hook. Also when setting a device online, dev_open() already calls dev_set_rx_mode(). So a manual modeset is only necessary from the recovery path. Signed-off-by: Julian Wiedmann Signed-off-by: David S.
