net/ice: get VF hardware index in DCF

The DCF (Device Config Function) needs the hardware index of the VFs to
control the flow setting. And also if the VF resets, the index may be
changed, so it should handle this in VF reset event.

net/ice: handle PF initialization by DCF

The DCF (Device Config Function) works at the user PF level, it can't
access the real PF hardware directly. So it will pass through the PF's
AdminQ command by the DCF's mailbox.

And the DCF is mainly used to control the flow setting of other VFs, so
it only needs to initialize some core functions related to the flow.

net/ice: export DDP definition symbols

it is a pure software design to control the advance functionality (such

The DCF (Device Config Function) feature shares the core functions of

net/ice: handle AdminQ command by DCF

The DCF (Device Config Function) splits the AdminQ command into two
parts: one is the descriptor of AdminQ command, the other is the buffer
of AdminQ command (the descriptor has BUF flag set). When both of them
are received by the PF, the PF will handle them as one command.

And also, the filled descriptor and buffer of the response will be sent
back to DCF one by one through the virtchnl from PF.

net/ice/base: discover and store size of available flash

When reading from the NVM using a flat address, it is useful to know the
upper bound on the size of the flash contents. This value is not stored

0xFFFFFF).

Use a while loop to bisect the upper and lower bounds by reading one
byte at a time. On a failed read, lower the maximum bound. On
a successful read, increase the lower bound.

net/ice/base: store NVM version in extracted format

Currently the NVM and Option ROM version information is stored in
a minimal format. The ice_get_nvm_version function exists to extract
this information for display.

This needlessly complicates using these fields as the extraction
function must be called to parse the NVM and Option ROM data. Further
confusion occurs because the prefix of "oem_" is used for the Option
ROM version. This appears to have been done because the Option ROM data
was requested for display by OEMs.

Refactor this code so that the NVM version and Option ROM version
components are extracted immediately.

Introduce a new struct ice_orom_info which will store the Option ROM
major, build, and patch numbers. Introduce the new major_ver and
minor_ver fields to store the NVM version in its high and low byte
components.

Remove the ice_get_nvm_version function. Instead, use the same logic to
convert the fields read from the NVM into the extracted format.

This simplifies use of these fields as they will be stored already
parsed, without needing to use the bit masks or call
ice_get_nvm_version.

- Call ice_test_and_clear_bit() over calling ice_is_bit_set() then

- Remove 'chrs' variable in ice_add_prof_id_flow() as it's not being
  used for anything.
- Return result directly instead of assigning to variable then

- Reduce scope, and don't initialize, 'or_vsig' in

- Return error immediately in ice_add_prof_id_vsig(). Since the memory
  wasn't allocated, there is no need to goto and attempt to free memory.
- Show that values 37-38 are reserved in ice_flow_avf_hdr_field as the
  other reserved values are shown.
- Fix RCT ordering
- Remove initialization of values that aren't needed
- Fix function headers to match function names
- Use offsetof instead of calculating ourselves in ice_pkg_buf_alloc()
- In ice_rem_prof(), do not set status to ICE_SUCCESS as, due to code
  flow, this will always be ICE_SUCCESS.

net/hns3: fix configuring RSS hash when rules are flushed

Currently, when performing test case as follow:
1. Run testpmd application based on hns3 network engine with multiple
   receive queues(--rxq=N --txq=N, N>1).
2. Create the special RSS rules by "create flow ..." command in the
   command prompt of the testpmd application.
3. Flush the RSS rules created in step 2 by "flow flush ..." command.
4. Enable RSS by "port config all rss all" command.
In step 4, the command exeuctes successfully. This phenomenon is
inconsistent with the expectation. The API function named
rte_eth_dev_rss_hash_update called in the command should return error

net/hns3: fix RSS indirection table configuration

For the current hns3 PMD driver, there are some RSS related bugs at
the following scenes:
1. Start the application with the number of Rx queues equals 1(--rxq=1),
   modify the number of Rx queue to some number greater than 1 during
   normal operation. As a result, upper application can't receive packets
   from multiple rx queues.
2. Start testpmd application with the option disable-rss and the number
   of Rx queue is greater than 1(--disable-rss --rxq=N, N>1). As a result,
   upper application still can receive packets from multiple rx queues.

The root cause as below:
There are some error configuration in the RSS indirection table of hns3
network engine.

This patch fixes them with the following modification.
1. When RSS size is changed, we need to update RSS redirection table
   maintained by driver and configure them to hardware. Besides, during

net/hns3: fix status after repeated resets

Currently, when performing the following test case:

2. Inject reset(global/IMP reset) repeatedly.
After the reset, the network port can't link up.

In the RESET_STAGE_DEV_INIT stage of the reset process, the driver will
reinitialize the hardware. If global/IMP reset occurs at this time
again, the operation of reinitialize the hardware will fail because that
firmware don't respond to the configuration commands issued by driver.
In current driver, when failed to reinitialize the hardware, rollback
operation is done, such as clearing the relevant configuration of the
command queue registers.

If firmware detects that the function's command queue register is not
configured correctly, it will not complete the reset related hardware
configuration for this function, resulting in that driver can't detect
that the hardware reset has been completed. And then the reset process

registers when failed to reinitialize the hardware in the

net/hns3: fix default error code of command interface

interface function named hns3_cmd_send to issues command to the

returned by firmware to driver.

As the design of error code, when device is resetting hns3_cmd_send will
only return -EBUSY or -EIO. But we found that if desc_ret is in

to query some table item, hns3_cmd_send also return -EIO. This
phenomenon will affect the processing logic for the return value.

hns3_cmd_convert_err_code called by hns3_cmd_send, matches the default

Currently there is a certain probability of the unexpected ol_flag of

1. The member variable named ol_flag of the structure named rte_mbuf is

   operation, the driver should assign value to the ol_flag of the first
   segment, not to the ol_flag of the last segment.

This patch fixes it with the following modification in the

1. Where the first write operation in the '.rx_pkt_burst' ops

2. In the static function named hns3_rx_set_cksum_flag, the last
   rte_mbuf's ol_flags should be assigned when processing multi-segment.
