net: hns3: refine the process when PF set VF VLAN · 204ebcf9

CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=190cd8a72b01

----------------------------------------------------------------------

Currently, when PF set VF VLAN, it sends notify mailbox to VF
if VF alive. VF stop its traffic, and send request mailbox
to PF, then PF updates VF VLAN. It's a bit complex. If VF is
killed before sending request, PF will not set VF VLAN without
any log.

This patch refines the process, PF can set VF VLAN direclty,
and then notify the VF. If VF is resetting at that time, the
notify may be dropped, so VF should query it after reset finished.

----------------------------------------------------------------------

When adding port base VLAN, vf VLAN need to remove from HW and modify
the vlan state in vf VLAN list as false. If the periodicity task is
freeing the same node, it may cause "use after free" error.
This patch adds a vlan list lock to protect the vlan list.

commit c0f46de3
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4YXIM
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c0f46de30c96

----------------------------------------------------------------------

Currently, Port base vlan is initiated by PF and configured to its VFs,
by using command "ip link set <pf name> vf <vf id> vlan <vlan id>".
When a global reset was triggered, the hardware vlan table and the soft
recorded vlan information will be cleared by PF, and restored them until
VFs were ready. There is a short time window between the table had been
cleared and before table restored. If configured a new port base vlan tag
at this moment, driver will check the soft recorded vlan information,
and find there hasn't the old tag in it, which causing a warning print.

Due to the port base vlan is managed by PF, so the VFs's port base vlan
restoring should be handled by PF when PF was ready.

This patch fixes it.

CVE: NA

----------------------------------------------------------------------

If the MAC address A is configured to vport A and then vport B. The MAC
address of vport A in the hardware becomes invalid. If the address of
vport A is changed to MAC address B, the driver needs to delete the MAC
address A of vport A. Due to the MAC address A of vport A has become
invalid in the hardware entry, so "-ENOENT" is returned. In this case, the
"used_umv_size" value recorded in driver is not updated. As a result, the
MAC entry status of the software is inconsistent with that of the hardware.

Therefore, the driver updates the umv size even if the MAC entry cannot be
found. Ensure that the software and hardware status is consistent.

Since some interrupt states may be cleared by hardware, the driver
may receive an empty interrupt. Currently, the VF driver directly
disables the vector0 interrupt in this case. As a result, the VF
is unavailable. Therefore, the vector0 interrupt should be enabled
in this case.

One of the flags is PTR_MAYBE_NULL which indicates a pointer
may be NULL. This patch switches the qualified reg_types to
