[PATCH net-next 0/5] net: hns3: misc updates for -next

[Huazhong Tan]

This series includes some misc updates for the HNS3 ethernet driver.

#1 adds support for 1280 queues
#2 adds mapping for BAR45 which is needed by RoCE client.
#3 extend the interrupt resources.
#4&#5 add support to query firmware's calculated shaping parameters.

[PATCH net-next 1/5] net: hns3: add support for 1280 queues

[Huazhong Tan]

From: Yonglong Liu <liuyonglong@huawei.com>

For DEVICE_VERSION_V1/2, there are total 1024 queues and
queue sets. For DEVICE_VERSION_V3, it increases to 1280,
and can be assigned to one pf， so remove the limitation
of 1024.

To keep compatible with DEVICE_VERSION_V1/2 and old driver
version, the queue number is split into two part:
tqp_num(range 0~1023) and ext_tqp_num(range 1024~1279).

[PATCH net-next 2/5] net: hns3: add support for mapping device memory

[Huazhong Tan]

For device who has device memory accessed through the PCI BAR4,
IO descriptor push of NIC and direct WQE(Work Queue Element) of
RoCE will use this device memory, so add support for mapping
this device memory, and add this info to the RoCE client whose
new feature needs.

[PATCH net-next 3/5] net: hns3: add support for pf querying new interrupt resources

[Huazhong Tan]

From: Yufeng Mo <moyufeng@huawei.com>

For HNAE3_DEVICE_VERSION_V3, a maximum of 1281 interrupt
resources are supported. To utilize these new resources,
extend the corresponding field or variable to 16bit type,
and remove the restriction of NIC client that only use a
maximum of 65 interrupt vectors. In addition, the I/O address
of the extended interrupt resources are different, so an extra
handler is needed.

Currently, the total number of interrupts is the sum of RoCE's
number and RoCE's offset (RoCE is in front of NIC), since
the number of both NIC and RoCE are same. For readability,
rewrite the corresponding field of the command, rename the
RoCE's offset field as the number of NIC interrupts, then
the total number of interrupts is sum of the number of RoCE
and NIC, and replace vport->back with hdev in
hclge_init_roce_base_info() for simplifying the code.

[PATCH net-next 4/5] net: hns3: add support to utilize the firmware calculated shaping parameters

[Huazhong Tan]

From: Yonglong Liu <liuyonglong@huawei.com>

Since the calculation of the driver is fixed, if the number of
queue or clock changed, the calculated result may be inaccurate.

So for compatible and maintainable, add a new flag to tell the
firmware to calculate the shaping parameters with the specified
rate.
