To facilitate code maintenance and compatibility, #1 and #2 add
device version to replace pci revision, #3 to #9 adds support for
querying device capabilities and specifications, then the driver
can use these query results to implement corresponding features
(some features will be implemented later).
And #10 is a minor cleanup since too many parameters for
hclge_shaper_para_calc().
Guangbin Huang (9):
net: hns3: add device version to replace pci revision
net: hns3: delete redundant PCI revision judgement
net: hns3: add support to query device capability
net: hns3: use capability flag to indicate FEC
net: hns3: use capabilities queried from firmware
net: hns3: add debugfs to dump device capabilities
net: hns3: add support to query device specifications
net: hns3: replace the macro of max tm rate with the queried
specification
net: hns3: add a check for device specifications queried from firmware
Huazhong Tan (1):
net: hns3: add a structure for IR shaper's parameter in
hclge_shaper_para_calc()

From: Guangbin Huang <huangguangbin2@huawei.com>
To better identify the device version, struct hnae3_handle adds a
member dev_version to replace pci revision. The dev_version consists
of hardware version and PCI revision. The hardware version is queried
from firmware by an existing firmware version query command.

Fibre device of PCI revision 0x20 don't support autoneg, and the ops
get_autoneg() return AUTONEG_DISABLE so function hns3_nway_reset()
will return earlier than judging PCI revision.
Function hclge_handle_rocee_ras_error() don't need to judge PCI
revision again because its caller hclge_handle_hw_ras_error() has
judged once.

add support to query the device capability by expanding the

From: Guangbin Huang <huangguangbin2@huawei.com>
Currently, the revision of the pci device is used to identify
whether FEC is supported, which is not good for maintainability
and compatibility. So use a capability flag to do that.

From: Guangbin Huang <huangguangbin2@huawei.com>
In order to improve code maintainability and compatibility, the
capabilities of new features are queried from firmware.
The member flag in struct hnae3_ae_dev indicates not only
capabilities, but some initialized status. As capabilities bits
queried from firmware is too many, it is better to use new member
to indicate them. So adds member capabs in struce hnae3_ae_dev.

To improve code maintainability and compatibility, new commands
HCLGE_OPC_QUERY_DEV_SPECS for PF and HCLGEVF_OPC_QUERY_DEV_SPECS
for VF are introduced to query device specifications, instead of
statically defining specifications by checking the hardware version
or other methods.

Guangbin Huang, Huazhong Tan
From: Guangbin Huang <huangguangbin2@huawei.com>
The max tm rate is a fixed value(100Gb/s) now as it is defined by a
macro. In order to support other rates in different kinds of device,
it is better to use specification queried from firmware to replace
this macro.
As function hclge_shaper_para_calc() has too many arguments to add
more, so encapsulate its three arguments ir_b, ir_u, ir_s into a
structure.

From: Guangbin Huang <huangguangbin2@huawei.com>
The device specifications querying is unsupported by the old
firmware, in this case, these specifications are 0. However,
some specifications should not be 0 or will cause problem.
So after querying from firmware, some device specifications
are needed to check their value and set to default value if
their values are 0.

As function hclge_shaper_para_calc() has too many arguments to add
more, so encapsulate its three arguments ir_b, ir_u, ir_s into a
structure.
