Subject: [PATCH net-next 10/15] net: hns3: refactor PF rss init APIs with new common rss init APIs
From: Jie Wang <wangjie125@...wei.com>
This patch uses common rss init APIs to replace the old APIs in PF rss
module and deletes the old PF rss init APIs. Some related subfunctions and
macros are also modified in this patch.
