Subject: net/hns3: separate setting hash key
|
||
|
|
|
||
|
|
[ upstream commit fe9cc8b88babd0911d91dc194b35c7c352e2bf7b ]
|
||
|
|
|
||
|
|
The settings of hash key comes from the ethdev ops (like, dev_configure
|
||
|
|
and rss_hash_update) and rte_flow API. For the ethdev ops, driver has
|
||
|
|
to save it to rss_info::key in hns3_hw structure so as to it can be
|
||
|
|
restored when reset is triggered. While rte_flow API no need to use
|
||
|
|
this field to save, they has a global flow_rss_list to maintain all
|
||
|
|
rules which save hash key. And hash key can be restored by this rule
|
||
|
|
information during the reset phase.
