Subject: [PATCH AUTOSEL 5.2 034/249] net: mvpp2: cls: Extract the RSS context when parsing the ethtool rule

From: Sasha Levin <[email-masked]>

[ Upstream commit c561da68038a738f30eca21456534c2d1872d13d ]

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.
