[PATCH V2 net-next 00/10] code optimizations & bugfixes for HNS3 driver

[Huazhong Tan]

This patch-set includes code optimizations and bugfixes for the HNS3
ethernet controller driver.

[patch 1/10] removes the redundant core reset type

[patch 2/10 - 3/10] fixes two VLAN related issues

[patch 4/10] fixes a TM issue

[patch 5/10 - 10/10] includes some patches related to RAS & MSI-X error

Change log:
V1->V2: removes two patches which needs to change HNS's infiniband
	driver as well, they will be upstreamed later with the
	infiniband's one.

Huazhong Tan (1):
  net: hns3: remove redundant core reset

Jian Shen (2):
  net: hns3: don't configure new VLAN ID into VF VLAN table when it's
    full
  net: hns3: fix VLAN filter restore issue after reset

Weihang Li (6):
  net: hns3: add a check to pointer in error_detected and slot_reset

  net: hns3: add handling of two bits in MAC tunnel interrupts
  net: hns3: remove setting bit of reset_requests when handling mac
    tunnel interrupts
  net: hns3: add opcode about query and clear RAS & MSI-X to special
    opcode

[PATCH V2 net-next 01/10] net: hns3: remove redundant core reset

[Huazhong Tan]

Since core reset is similar to the global reset, so this
patch removes it and uses global reset to replace it.

[PATCH V2 net-next 02/10] net: hns3: don't configure new VLAN ID into VF VLAN table when it's full

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

VF VLAN table can only support no more than 256 VLANs. When user
adds too many VLANs, the VF VLAN table will be full, and firmware
will close the VF VLAN table for the function. When VF VLAN table
is full, and user keeps adding new VLANs, it's unnecessary to
configure the VF VLAN table, because it will always fail, and print
warning message. The worst case is adding 4K VLANs, and doing reset,
it will take much time to restore these VLANs, which may cause VF
reset fail by timeout.

[PATCH V2 net-next 03/10] net: hns3: fix VLAN filter restore issue after reset

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

In orginal codes, the driver only restore VLAN filter entries
for PF after reset, the VLAN entries of VF will lose in this
case.

This patch fixes it by recording VLAN IDs for each function
when add VLAN, and restore the VLAN IDs after reset.

[PATCH V2 net-next 05/10] net: hns3: add a check to pointer in error_detected and slot_reset

[Huazhong Tan]

From: Weihang Li <liweihang@hisilicon.com>

If we add a VF without loading hclgevf.ko and then there is a RAS error
occurs, PCIe AER will call error_detected and slot_reset of all functions,
and will get a NULL pointer when we check ad_dev->ops->handle_hw_ras_error.
This will cause a call trace and failures on handling of follow-up RAS
errors.

This patch check ae_dev and ad_dev->ops at first to solve above issues.

[PATCH V2 net-next 07/10] net: hns3: add handling of two bits in MAC tunnel interrupts

[Huazhong Tan]

From: Weihang Li <liweihang@hisilicon.com>

LINK_UP and LINK_DOWN are two bits of MAC tunnel interrupts, but previous
HNS3 driver didn't handle them. If they were enabled, value of these two
bits will change during link down and link up, which will cause HNS3
driver keep receiving IRQ but can't handle them.

This patch adds handling of these two bits of interrupts, we will record
and clear them as what we do to other MAC tunnel interrupts.

[PATCH V2 net-next 09/10] net: hns3: add opcode about query and clear RAS & MSI-X to special opcode

[Huazhong Tan]

From: Weihang Li <liweihang@hisilicon.com>

There are four commands being used to query and clear RAS and MSI-X
interrupts status. They should be contained in array of special opcodes
because these commands have several descriptors, and we need to judge
return value in the first descriptor rather than the last one as other
opcodes. In addition, we shouldn't set the NEXT_FLAG of first descriptor.

This patch fixes above issues.

[PATCH V2 net-next 10/10] net: hns3: delay and separate enabling of NIC and ROCE HW errors

[Huazhong Tan]

From: Weihang Li <liweihang@hisilicon.com>

All RAS and MSI-X should be enabled just in the final stage of HNS3
initialization. It means that they should be enabled in
hclge_init_xxx_client_instance instead of hclge_ae_dev(). Especially
MSI-X, if it is enabled before opening vector0 IRQ, there are some
chances that a MSI-X error will cause failure on initialization of
 NIC client instane. So this patch delays enabling of HW errors.
Otherwise, we also separate enabling of ROCE RAS from NIC, because
it's not reasonable to enable ROCE RAS if we even don't have a ROCE
driver.
