ntuple filters can specify an rss context to use for packet hashing and queue selection. When a filter is referencing an rss context, it should be invalid for that context to be deleted. A list of active ntuple filters and their associated rss contexts can be compiled by querying a device's ethtool_ops.get_rxnfc. This patch checks to see if any ntuple filters are referencing an rss context during context deletion, and prevents the deletion if the requested context is still in use.
