Subject: [PATCH net-next,v5 08/12] flow_offload: add wake-up-on-lan and queue to flow_action

These actions need to be added to support the ethtool_rx_flow interface.
The queue action includes a field to specify the RSS context, that is
set via FLOW_RSS flow type flag and the rss_context field in struct
ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that
rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS
was not set.

Signed-off-by: Pablo Neira Ayuso <pablo@...filter.org>

v5: add queue structure and context field, per Michal Kubecek.
