net/hns3: maximize queue number
The maximum number of queues for hns3 PF and VF driver is 64 based on
hns3 network engine with revision_id equals 0x21. Based on hns3 network
engine with revision_id equals 0x30, the hns3 PF PMD driver can support
up to 1280 queues, and hns3 VF PMD driver can support up to 128 queues.
The following points need to be modified to support maximizing queue
number and maintain better compatibility:
1) Maximizing the number of queues for hns3 PF and VF PMD driver In
current version, VF is not supported when PF is driven by hns3 PMD
driver. If maximum queue numbers allocated to PF PMD driver is less
than total tqps_num allocated to this port, all remaining number of
queues are mapped to VF function, which is unreasonable. So we fix
that all remaining number of queues are mapped to PF function.
Using RTE_LIBRTE_HNS3_MAX_TQP_NUM_PER_PF which comes from
configuration file to limit the queue number allocated to PF device
based on hns3 network engine with revision_id greater than 0x30. And
PF device still keep the maximum 64 queues based on hns3 network
engine with revision_id equals 0x21.
Remove restriction of the macro HNS3_MAX_TQP_NUM_PER_FUNC on the
maximum number of queues in hns3 VF PMD driver and use the value
allocated by hns3 PF kernel netdev driver.
2) According to the queue number allocated to PF device, a variable
array for Rx and Tx queue is dynamically allocated to record the
statistics of Rx and Tx queues during the .dev_init ops
implementation function.
3) Add an extended field in hns3_pf_res_cmd to support the case that
numbers of queue are greater than 1024.
4) Use new base address of Rx or Tx queue if QUEUE_ID of Rx or Tx queue
is greater than 1024.
5) Remove queue id mask and use all bits of actual queue_id as the
queue_id to configure hardware.
6) Currently, 0~9 bits of qset_id in hns3_nq_to_qs_link_cmd used to
record actual qset id and 10 bit as VLD bit are configured to
hardware. So we also need to use 11~15 bits when actual qset_id is
greater than 1024.
7) The number of queue sets based on different network engine are
different. We use it to calculate group number and configure to
hardware in the backpressure configuration.
8) Adding check operations for number of Rx and Tx queue user configured
when mapping queue to tc Rx queue numbers under a single TC must be
less than rss_size_max supported by a single TC. Rx and Tx queue
numbers are allocated to every TC by average. So Rx and Tx queue
numbers must be an integer multiple of 2, or redundant queues are not
available.
9) We can specify which packets enter the queue with a specific queue
number, when creating flow table rules by rte_flow API. Currently,
driver uses 0~9 bits to record the queue_id. So it is necessary to
extend one bit field to record queue_id and configure to hardware, if
the queue_id is greater than 1024.
