[PATCH V3 net 1/7] net: hns3: using user configure after hardware reset

[Jijie Shao]

From: Peiyang Wang <wangpeiyang1@huawei.com>

When a reset occurring, it's supposed to recover user's configuration.
Currently, the port info(speed, duplex and autoneg) is stored in hclge_mac
and will be scheduled updated. Consider the case that reset was happened
consecutively. During the first reset, the port info is configured with
a temporary value cause the PHY is reset and looking for best link config.
Second reset start and use pervious configuration which is not the user's.
The specific process is as follows:

+------+               +----+                +----+
| USER |               | PF |                | HW |

To avoid aboved situation, this patch introduced req_speed, req_duplex,
req_autoneg to store user's configuration and it only be used after
hardware reset and to recover user's configuration

Can any wording adjustments be a bit nicer?

An user configuration should be recovered after a reset occurred.

and the schedule will be updated. Consider also the case that reset happened

* Would you like to avoid another typo here?

* How do you think about to use imperative wordings for improved change descriptions?

[PATCH V3 net 2/7] net: hns3: direct return when receive a unknown mailbox message

[Jijie Shao]

From: Jian Shen <shenjian15@huawei.com>

Currently, the driver didn't return when receive a unknown
mailbox message, and continue checking whether need to
generate a response. It's unnecessary and may be incorrect.

[PATCH V3 net 4/7] net: hns3: release PTP resources if pf initialization failed

[Jijie Shao]

From: Peiyang Wang <wangpeiyang1@huawei.com>

During the PF initialization process, hclge_update_port_info may return an
error code for some reason. At this point,  the ptp initialization has been
completed. To void memory leaks, the resources that are applied by ptp
should be released. Therefore, when hclge_update_port_info returns an error
code, hclge_ptp_uninit is called to release the corresponding resources.

Wording suggestion:
   Add a jump target so that the corresponding resources are released
   with a hclge_ptp_uninit() call.

[PATCH V3 net 5/7] net: hns3: use appropriate barrier function after setting a bit value

There is a memory barrier in followed case. When set the port down,
hclgevf_set_timmer will set DOWN in state. Meanwhile, the service task has
different behaviour based on whether the state is DOWN. Thus, to make sure
service task see DOWN, use smp_mb__after_atomic after calling set_bit().

[PATCH V3 net 6/7] net: hns3: fix port vlan filter not disabled issue

[Jijie Shao]

From: Yonglong Liu <liuyonglong@huawei.com>

According to hardware limitation, for device support modify
VLAN filter state but not support bypass port VLAN filter,
it should always disable the port VLAN filter. but the driver
enables port VLAN filter when initializing, if there is no
VLAN(except VLAN 0) id added, the driver will disable it
in service task. In most time, it works fine. But there is
a time window before the service task shceduled and net device
being registered. So if user adds VLAN at this time, the driver
will not update the VLAN filter state,  and the port VLAN filter
remains enabled.

To fix the problem, if support modify VLAN filter state but not
support bypass port VLAN filter, set the port vlan filter to "off".

Fixes: 184cd221a863 ("net: hns3: disable port VLAN filter when support function level VLAN filter control")

[PATCH V3 net 7/7] net: hns3: fix kernel crash when devlink reload during initialization

[Jijie Shao]

From: Yonglong Liu <liuyonglong@huawei.com>

The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel
crash.

This patch fixes this by registering the devlink after
hardware initialization.
