openvswitch: Fix push/pop ethernet validation
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") Signed-off-by: Jaime Caamaño Ruiz <jcaamano@suse.com> Tested-by: Greg Rose <gvrose8192@gmail.com> Reviewed-by: Greg Rose <gvrose8192@gmail.com> Signed-off-by: David S.
