mainline inclusion from mainline-br26_refactor2 commit eaa5607db377 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...
----------------------------------------------------------------------
This patch firstly uses new hardware description struct hclge_comm_hw as child member of hclge_hw and deletes the original child memebers of hclge_hw. All the hclge_hw variables used in PF module is modified according to the new hclge_hw.
Secondly hclge_cmd_send is refactored to use hclge_comm_cmd_send APIs. The old functions called by hclge_cmd_send are deleted and hclge_cmd_send is kept to avoid too many meaningless modifications.
