The maximum number of queues for one TC hns3 PF PMD driver supported is
64 based on hns3 network engine with revision_id equals 0x21, while it
is expanded up to 512 on hns3 network engine with revision_id equals
0x30.
So the following points need to be modified to maintain better
compatibility.
1) Using a extended rss_size_max field as the maximum queue number of
one TC PF driver supported.
2) The data type of the RSS redirection table needs to be changed from
uint8_t to uint16_t.
3) rss_tc_mode modification
The bitwidth of tc_offset, meaning the rx queue index, has to expand
from 10 bit to 11 bits. The tc_size, meaning the exponent with base 2
of queues supported on TC, needs to expand from 3 bits to 4 bits.
4) RSS indirection table modification
Currently, a field with 7 bits width is used to record the queue
index for RSS indirection table. It means that PF needs to expand the
queue index field to 9 bits. As the RSS indirection table config
command reserved 4 bytes to configure the RSS queue index, a extern
field can be added. So an entries of RSS indirection table queue
index has two fields to set: rss_result_l and rss_result_h, while
rss_result_l records the lower 8 bits and rss_result_h records the
higher 1 bit.
In addition, 2~4 modifications is also compatible with hns3 VF PMD
driver.
