Subject: [PATCH net 3/4] net: hns3: fix RMW issue for VLAN filter switch

From: Jian Shen <[email protected]>

According to the user manual, the ingress and egress VLAN filter
are configured at the same time. Currently, hclge_init_vlan_config()
and hclge_set_vlan_spoofchk() will both change the VLAN filter
switch. So it's necessary to read the old configuration before
modifying it.

Subject: [PATCH net 2/4] net: hns3: fix VF VLAN table entries inconsistent issue

From: Jian Shen <[email protected]>

Currently, if VF is loaded on the host side, the host doesn't
clear the VF's VLAN table entries when VF removing. In this
case, when doing reset and disabling sriov at the same time the
VLAN device over VF will be removed, but the VLAN table entries
in hardware are remained.

This patch fixes it by asking PF to clear the VLAN table entries for
VF when VF is removing. It also clears the VLAN table full bit
after VF VLAN table entries being cleared.

Subject: [PATCH net 1/4] net: hns3: fix "tc qdisc del" failed issue

From: Yonglong Liu <[email protected]>

The HNS3 driver supports to configure TC numbers and TC to priority
map via "tc" tool. But when delete the rule, will fail, because
the HNS3 driver needs at least one TC, but the "tc" tool sets TC
number to zero when delete.

This patch makes sure that the TC number is at least one.

unload. In this case, the VLAN id will remain in the VLAN
table. This patch fixes it.
