Subject: [PATCH net] openvswitch: Fix push/pop ethernet validation
Date: Wed, 31 Oct 2018 18:52:03 +0100 [thread overview]
Message-ID: <20181031175203.23808-1-jcaamano@suse.com> (raw)
When there are both pop and push ethernet header actions among the
actions to be applied to a packet, an unexpected EINVAL (Invalid
argument) error is obtained. This is due to mac_proto not being reset
correctly when those actions are validated.
Reported-at:
https://mail.openvswitch.org/pipermail/ovs-discuss/2018-October/047554.html
Fixes: 91820da6ae85 ("openvswitch: add Ethernet push and pop actions")
