This patch add support config dscp map to tc by implementing ieee_setapp
and ieee_delapp of struct dcbnl_rtnl_ops. Driver will convert mapping
relationship from dscp-prio to dscp-tc.

initialization
Currently in driver initialization process, driver will set shapping
parameters of tm port to default speed read from firmware. However, the
speed of SFP module may not be default speed, so shapping parameters of
tm port may be incorrect.
To fix this problem, driver sets new shapping parameters for tm port
after getting exact speed of SFP module in this case.

The hns3 driver header file uses the structure of other files, but does
not include corresponding file, which causes a check warning that the
header file is not self-contained.
Therefore, the required header file is included in the header file, and
the structure declaration is added to the header file to avoid cyclic
dependency of the header file.

Currently, driver will send command to firmware to query pfc packet number
when user uses dcb tool to get pfc parameters. However, the periodic
service task will also periodically query and record MAC statistics,
including pfc packet number.
As the hardware registers of statistics is cleared after reading, it will
cause pfc packet number of MAC statistics are not correct after using dcb
tool to get pfc parameters.
To fix this problem, when user uses dcb tool to get pfc parameters, driver
updates MAC statistics firstly and then get pfc packet number from MAC
statistics.

Currently, user gets qset shaper parameters by implementing debugfs
command "echo dump qs shaper > cmd", this command will dump info in
dmesg. It's unnecessary and heavy.
As there is "tm_qset" file in tm directory for dump qset info, to
optimize these command, merge qset shaper parameters to tm_qset
file and use cat command to get them.
The display style is below:
$ cat tm_qset
ID MAP_PRI LINK_VLD MODE DWRR IR_B IR_U IR_S BS_B BS_S FLAG

Currently, user gets some tm info by implementing debugfs command
"echo dump tm > cmd", this command will dump info in dmesg. It's
unnecessary and heavy.
In addition, the info of this command mixes info of qset, priority,
pg and port. Qset and priority have their own command to get info of
themself, so can remove info of qset and priority from this command.
To optimize it, create two new files "tm_pg", "tm_port" in tm directory
and use cat command to separately get info of pg and port.
The display style is below:
$ cat tm_pg
ID PRI_MAP MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S ...

Currently, the debugfs command for tm map is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create a single file
"tm_map" for it, and query it by command "cat tm_map",
return the result to userspace, rather than record in dmesg.
As user can't specify queue id in cat command, driver will return info
of all queue id.
The display style is below:
$ cat tm_map
queue_id qset_id pri_id tc_id

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).

Currently when there is share buffer in the SSU(storage
switching unit), the low waterline for RX private buffer is
too low to keep the hardware running. Hardware may have
processed all the packet stored in the private buffer of the
low waterline before the new packet comes, because hardware
only tell the peer send packet again when the private buffer
is under the low waterline.
So this patch only allocate RX private buffer if there is
enough buffer according to hardware user manual.
This patch also reserve some buffer for reusing when TC num
is less than or equal to 2, and change PAUSE_TRANS_GAP &
HCLGE_NON_DCB_ADDITIONAL_BUF according to hardware user
manual.

Ethtool -L option with the combined parameter is for changing the number of
multi-purpose channels of the specified network device. Under the current
scheme, the user configuration information will be lost after the reset or
TC information changed.
This patch fixes this issue. By default, this configuration is set to the
minimum between the number of queues for each enabled TCs and the maximum
number support available in the hardware. When there is a user
configuration, regardless of the reset or TC information change, it should
keep the user's configuration while it is under the hardware limits,
otherwise set to the maximum number support available in the hardware.

Before setting tm related configuration to hardware, driver
needs to check the configuration provided by user is valid.
Currently hclge_ieee_setets and hclge_setup_tc both implement
their own checking, which has a lot in common.
This patch addes hclge_dcb_common_validate to do the common
checking. The checking in hclge_tm_prio_tc_info_update
and hclge_tm_schd_info_update is unnecessary now, so change
the return type to void, which removes the need to do error
handling when one of the checking fails.
Also, ets->prio_tc is indexed by user prio and ets->tc_tsa is
indexed by tc num, so this patch changes them to use different
index.

Hardware as such consists of two types of cofiguration of 6 level
