Subject[PATCH net-next] vmxnet3: allow rx flow hash ops only when rss is enabled
Date
It makes sense to allow changes to get/set rx flow hash callback only
when rss is enabled. This patch restricts get_rss_hash_opts and
set_rss_hash_opts methods to allow querying and configuring different
Rx flow hash configurations only when rss is enabled
