Subject: [PATCH 159/189] net/hns3: fix IPv4 RSS
When user only use 'ipv4' to set 'rss_hf', hns3 will enable
all tuple fields for 'ipv4' flow. But if user use 'ipv4-tcp'
, 'ipv4' and 'l4-src-only' to set 'rss_hf', driver does not
enable all tuple fields for 'ipv4' flow.
Fixes: 806f1d5ab0e3 ("net/hns3: set RSS hash type input configuration")
