[PATCH net-next 4/5] net: mvpp2: cls: Extract the RSS context when parsing the ethtool rule

From: Maxime Chevallier
Date: Fri May 24 2019 - 06:09:15 EST


ethtool_rx_flow_rule_create takes into parameter the ethtool flow spec,
which doesn't contain the rss context id. We therefore need to extract
it ourself before parsing the ethtool rule.

The FLOW_RSS flag is only set in info->fs.flow_type, and not
info->flow_type.
