Subject: [PATCH 5.16 0737/1017] net: hns3: clean residual vf config after disable sriov
From: Peng Li <lipeng321@...wei.com>
[ Upstream commit 671cb8cbb9c9e24b681d21b1bfae991e2386ac73 ]
After disable sriov, VF still has some config and info need to be
cleaned, which configured by PF. This patch clean the HW config
and SW struct vport->vf_info.
Fixes: fa8d82e853e8 ("net: hns3: Add support of .sriov_configure in HNS3 driver")
