commit 715c58e9
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=715c58e94f0d78907bfccde12c2ca5236502c53e

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

To implement the system suspend/resume functions, the NIC driver needs
to support:
1. When the system enters the suspend mode, the driver needs to
implement the suspend callback function of the NIC device. The driver
needs to mute the device, stop all RX/TX activities of the device, and
unmap the interrupt.
2. When the system enters the resume mode, the driver needs to
implement the resume callback function of the NIC device and restore
the device to the state before suspension.

When the system enters the suspend and resume mode, the NIC driver
actually executes the PF function reset process.

When the PFs are suspending/resuming, VFs also enter the suspend/resume
state because the PFs trigger the VFs to reset, therefore no operation
is required when the VF pci_driver is suspending or resuming.

For DEVICE_VERSION_V3, the hardware supports to match specified
data in the specified offset of packet payload. Each layer can
have one offset, and can't be masked when configure flow director
rule by ethtool command. The layer is selected based on the
flow-type, ether for L2, ip4/ipv6 for L3, and tcp4/tcp6/udp4/udp6
for L4. For example, tcp4/tcp6/udp4/udp6 rules share the same
user-def offset, but each rule can have its own user-def value.

For the user-def field of ethtool -N/U command is 64 bits long.
The bit 0~15 is used for user-def value, and bit 32~47 for user-def
offset in HNS3 driver.

Currently, the flow director rule of aRFS is configured in
the IO path. It's time-consuming. So move out the configuration,
and configure it asynchronously. And keep ethtool and tc flower
rule using synchronous way, otherwise the application maybe
unable to know the rule is installed or pending.

Add a state member for each flow director rule to indicate the
rule state. There are 4 states:
TO_ADD: the rule is waiting to add to hardware
TO_DEL: the rule is waiting to remove from hardware
DELETED: the rule has been removed from hardware. It's a middle
        state, used to remove the rule node in the fd_rule_list.
ACTIVE: the rule is already added in hardware

For asynchronous way, when receive a new request to add or delete
flow director rule by aRFS, update the rule list, then request to
schedule the service task to finish the configuration.

For synchronous way, when receive a new request to add or delete
flow director rule by ethtool or tc flower, configure hardware
directly, then update the rule list if success.

The hardware supports to parse and match the traffic class field

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.
