Subject: net/iavf: fix RSS when VF port closed
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7dd0d9f29f426c7355427a6f1ce439ff84e433e2;p=dpdk.git

net/iavf: fix RSS when VF port closed

Check the VF RSS offload flag and ignore relative operation when
iavf hash uninit to avoid reset/close error.

Fixes: 7be10c3004be ("net/iavf: add RSS configuration for VF")
