mainline inclusion from mainline-master commit 9667b814387c category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4Q02P CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently PF stores its rss parameters in vport structure. VF stores rss configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters are same beween PF and VF. The two set of rss parameters are redundent and may add extra bugfix work.
So this patch creates new common rss parameter struct(hclge_comm_rss_cfg) to unify PF and VF rss configurations.
These new structures will be used to unify rss configurations in PF and VF rss APIs in next patches.
