Subject: [PATCH net 4/4] net: hns3: fix rx VLAN offload state inconsistent issue
Date: Mon, 19 Jul 2021 17:13:08 +0800 [thread overview]
Message-ID: <1626685988-25869-5-git-send-email-huangguangbin2@huawei.com> (raw)
In-Reply-To: <1626685988-25869-1-git-send-email-huangguangbin2@huawei.com>
From: Jian Shen <shenjian15@huawei.com>
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")
