Subject: [PATCH net-next 8/9] net: hns3: refactor the coalesce related struct
From: Yunsheng Lin <linyunsheng@...wei.com>
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.
