    Subject[PATCH 5.13 114/223] net: hns3: fix rx VLAN offload state inconsistent issue
    Date
    From: Jian Shen <shenjian15@huawei.com>

    [ Upstream commit bbfd4506f962e7e6fff8f37f017154a3c3791264 ]

    Currently, VF doesn't enable rx VLAN offload when initializating,
    and PF does it for VFs. If user disable the rx VLAN offload for
    VF with ethtool -K, and reload the VF driver, it may cause the
    rx VLAN offload state being inconsistent between hardware and
    software.

    Fixes it by enabling rx VLAN offload when VF initializing.

    Fixes: e2cb1dec9779 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support")
