From: "Min Hu (Connor)" humin29@huawei.com
In current HNS3 PMD, Rx/Tx bytes and imissed from packet stats are not implemented.
This patch implemented Rx/Tx bytes using soft counters. Rx/Tx bytes stats will be enabled if the macro RTE_LIBRTE_HNS3_PMD_SOFT_COUNTERS is defined. Also, Rx imissed stats was in implemented in this patch.

When link information is updated in the firmware, the link information is updated first and then the link status is updated. In a 1s periodic task, PF driver queries the link information and then obtains link status. It may lead to a 1s time difference for obtaining valid link information when the port is up. Therefore, the query order of driver should be reversed to the order of firmware.

When the hardware link status changes, the firmware proactively reports the link status change message, and then driver update link status. This feature is lack of a switch to control in pf driver. Otherwise, this feature does not take effect when the kernel PF driver that supports the feature is not loaded.

The normal operation of electrical interface devices depends on the initialization and configuration of the PHY chip. The task of driving the PHY chip is implemented in some firmware versions. If firmware supports the phy driver, it will report a capability flag to driver in probing process. The driver determines whether to support electrical device based on the capability bit. If supported, the driver set a flag indicating that the firmware takes over the PHY, and then the firmware intializes the PHY.
This patch supports the query of link status and link info, and existing basic features for electrical device.

Currently, statistics may overflow in some scenarios.
For example, if HW statistics are reset by stats reset operation, but there are still a lot of residual packets exist in the HW queues and these packets are error packets, flip may occurred because the ipacket is obtained by substracting the number of software error packets from the number of HW received packets.
This patch verifies the calculation and returns 0 when overflow may occur.

There are two scenarios that command queue uninit performed concurrently with the firmware command: asynchronous command and timeout command.
For asynchronous command, if a large number of functions send commands, these commands may need to be queued to wait for firmware processing. If a function is uninited suddenly, CMDQ clearing and firmware processing may be performed concurrently.
For timeout command, if the command failed due to busy scheduling of firmware, this command will be processed in the next scheduling. And this may lead to concurrency.
The preceding concurrency may lead to a firmware exceptions.
This patch add a waiting time to ensure the firmware complete the processing of left over command when PMD uninit.

Currently, during the VF reset, the VF will send a MBX to inform PF to reset it and the disable command bit will be set whether the MBX is successful. Generally, multiple reset attempts are made after a failure. However, because the command is diabled, all subsequent reset will all fail.
This patch disable the command only after the MBX message is successfully.

When jumbo frame is enabled, the MTU size needs to be modified based on 'max_rx_pkt_len'. Driver needs to check the validity of 'max_rx_pkt_len'. And it should be in the range of HNS3_DEFAULT_FRAME_LEN and HNS3_MAX_FRAME_LEN. Otherwise, it may cause that the MTU size is inconsistent with jumbo frame offload.

Hi Lijun,
Is this for next release or current release? We are a day away from the -rc3 and a week (almost) away from the actual release, it is safer to limit the patches to fixes at this stage.
If above set is for this release, can you please make a new version to have only fixes, and leave the new supports and refactoring and not important fixes to next release?
Thanks, ferruh

Yes, I've been aware of our expectations and requirements of each rc. Therefore, we have selected some new support items that have been developed and tested in the roadmap and hope to integrate them in the rc3. Some key bug fixes are expected to be fixed in the current version as soon as possible.
Thanks, ferruh

Still not sure about getting new small functionality in the last day of the -rc3, what do you think get the fixes and push the new functionality to next release?
Technically new features should be sent _before_ the proposal deadline, December 20, and we are more flexible for the drivers but there should be a deadline eventually.
