Hello dpdk-uesrs.
I am new member of this list.
thanks for any help.
I am currently working on adding RSS to our PMD driver which will
eventually configure our hardware.
I have a question in regards to DPDK framework behavior in regards to RSS.
Should i expect DPDK framework to configure my PMD to some default
indirection table in case the application set the device to use RSS?
(mq_mode = ETH_MQ_RX_RSS)
I came accross some good post on DPDK-RSS which says DPDK should configure
default table:
http://galsagie.github.io/dpdk%20design%20tips/dpdk/nfv/2015/02/26/dpdk-tips-1/
The question is:
will DPDK call the RSS API i register with some default table in case
application enabled RSS? or should i read this flag in my dev_configure()
callback and construct this table?
APIs i have registered:
reta_update
reta_query
rss_hash_update
rss_hash_conf_get
Testing it does not show that DPDK calls to these API in case of flag
enable.
(It does call them in case application call them explicitly)
