Subject: [PATCH 4/9] s390: qeth driver fixes [1/6]
Date: Wed, 6 Sep 2006 17:05:36 +0200 [thread overview]
Message-ID: <200609061705.36971.fpavlic@de.ibm.com> (raw)
[PATCH 4/9] s390: qeth driver fixes [1/6]
From: Frank Pavlic <fpavlic@de.ibm.com>
- Drop incoming packets with vlan_tag set
if card->vlangrp is not set.
- use always vlan_hwaccel_rx to pass
vlan frames to the stack.
- fix recovery problem. Device was recovered
properly but still not working.
netif_carrier_on call right before
recovery start fixes it.
