mainline inclusion from mainline-v5.19-rc1 commit 71b215f36dca category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5DGNU CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently hns3 driver misuses the VF rss size to initialize the PF rss size in hclge_tm_vport_tc_info_update. So this patch fix it by checking the vport id before initialization.
