From 9bc727a9d5e5c47015db118db407cbada1081a1e Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Fri, 9 Mar 2018 10:37:03 +0800 Subject: net: hns3: refactor the coalesce related struct This patch refoctors the coalesce related struct by introducing the hns3_enet_coalesce struct, in order to fix the coalesce configuation lost problem when changing the channel number.
