Currently, there are two different sets of special command codes in PF and

So this patch unifes the special command codes and deletes the bool param

In this case when VF just uses one TC and its rx packets contain priority,
and if the priority is not mapped to TC0, as other TCs of VF is not valid,
hardware always put this kind of packets to the queue 0. It cause this kind
of packets of VF can not be used RSS function.

To fix this problem, set tc mode of all unused TCs of VF to the setting of

ethernet: constify references to netdev->dev_addr in drivers

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.

No functional changes.

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.

net: hns3: fix ROCE base interrupt vector initialization bug

net: hns3: fix ROCE base interrupt vector initialization bug

[ Upstream commit beb27ca451a57a1c0e52b5268703f3c3173c1f8c ]

Currently, NIC init ROCE interrupt vector with MSIX interrupt. But ROCE use
pci_irq_vector() to get interrupt vector, which adds the relative interrupt
vector again and gets wrong interrupt vector.

So fixes it by assign relative interrupt vector to ROCE instead of MSIX
interrupt vector and delete the unused struct member base_msi_vector
declaration of hclgevf_dev.

net: hns3: ignore reset event before initialization process is done

Currently, if there is a reset event triggered by RAS during device in
initialization process, driver may run reset process concurrently with
initialization process. In this case, it may cause problem. For example,
the RSS indirection table may has not been alloc memory in initialization
process yet, but it is used in reset process, it will cause a call trace

net: hns3: change hclge/hclgevf workqueue to WQ_UNBOUND mode

Currently, the workqueue of hclge/hclgevf is executed on
the CPU that initiates scheduling requests by default. In
stress scenarios, the CPU may be busy and workqueue scheduling
is completed after a long period of time. To avoid this
situation and implement proper scheduling, use the WQ_UNBOUND
mode instead. In this way, the workqueue can be performed on
a relatively idle CPU.

net: hns3: fix vf reset workqueue cannot exit

The task of VF reset is performed through the workqueue. It checks the
value of hdev->reset_pending to determine whether to exit the loop.
However, the value of hdev->reset_pending may also be assigned by
the interrupt function hclgevf_misc_irq_handle(), which may cause the
loop fail to exit and keep occupying the workqueue. This loop is not
necessary, so remove it and the workqueue will be rescheduled if the
reset needs to be retried or a new reset occurs.
