The hardware supports to parse and match the traffic class field
of IPv6 packet for flow director, uses the same tuple as ip tos.
So removes the limitation of configure 'tclass' by driver.

Currently, there are too many branches for hclge_fd_convert_tuple().
And it may be more when add new tuples. Refactor it by sorting the
tuples according to their length. So it only needs several KEY_OPT
now, and being flexible to add new tuples.

If the imp-controlled PHYs feature is enabled, driver can not
call phy driver interface to set loopback anymore and needs
to send command to firmware to start phy loopback.

Driver reuses the existing firmware command 0x0315 to start
phy loopback, just add a setting bit in this command. As this
command is not only for serdes loopback anymore, rename this
command to "xxx_COMMON_LOOPBACK", and modify function name,
macro name and logs related to it.

When the imp-controlled PHYs feature is enabled, phydev is NULL.
In this case, the autoneg is always off when user uses ethtool -a
command to get pause parameters because  hclge_get_pauseparam()
uses phydev to check whether device is TP port. To fit this new
feature, use media type to check whether device is TP port.

And when user set pause parameters, these parameters need to
always set to mac, no matter whether autoneg is off.

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.

For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.

To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.

For the rss size may be larger than 256, so the type of
rss_indirection_tbl of struct hclge_vport should be changed to
u16 as well.

Currently, the HNS3 driver only supports offload for tc number
and prio_tc. This patch adds support for other qopts, including
queues count and offset for each tc.

When enable tc mqprio offload, it's not allowed to change
queue numbers by ethtool. For hardware limitation, the queue
number of each tc should be power of 2.

For the queues is not assigned to each tc by average, so it's

----------------------------------------------------------------------

For DEVICE_VERSION_V2, the hardware only supports max two layer
VLAN tags, including port based tag inserted by hardware, tag in
tx buffer descriptor(get from skb->tci) and tag in packet.

For transmit packet:
If port based VLAN disabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the Outer_VLAN_TAG field
(tag near to DMAC) of tx buffer descriptor, otherwise it may
be inserted after the tag in packet.

If port based VLAN enabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the VLAN_TAG field (tag
far to DMAC) of tx buffer descriptor, otherwise it may be
conflicted with port based VLAN, and raise a hardware error.

For receive packet:
The hardware will strip the VLAN tags and fill them in the rx
buffer descriptor, no matter port based VLAN enable or not.
Because port based VLAN tag is useless for stack, so vf driver
needs to discard the port based VLAN tag get from rx buffer
descriptor when port based VLAN enabled.

So vf must know about the port based VLAN state.

For DEVICE_VERSION_V3, the hardware provides some new
configuration to improve it.

For transmit packet:
When enable tag shift mode, hardware will handle the VLAN tag
in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with
port based VLAN. And hardware also make sure the tag before
the tag in packet. So vf driver doesn't need to specify the tag
position according to the port based VLAN state anymore.

For receive packet:
When enable discard mode, hardware will strip and discard the
port based VLAN tag, so vf driver doesn't need to identify it
from rx buffer descriptor.

So modify the port based VLAN configuration, simplify the process
for vf handling the VLAN tag.

For DEVICE_VERSION_V2, the hardware supports enable tx and rx
promiscuous separately. But tx or rx promiscuous is active for
unicast, multicast and broadcast promiscuous simultaneously.
To support traffics between functions belong to the same port,
we always enable tx promiscuous for broadcast promiscuous, so
tx promiscuous for unicast and multicast promiscuous is also
enabled.

For DEVICE_VERSION_V3, the hardware decouples the above
relationship. Tx unicast promiscuous, rx unicast promiscuous,
tx multicast promiscuous, rx multicast promiscuous, tx broadcast
promiscuous and rx broadcast promiscuous can be enabled separately.

So add support for the new promiscuous command.

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.
