[PATCH net-next 2/7] net: hns3: refactor function hclge_parse_capability()
From: Guangbin Huang <hidden>
Date: 2021-08-28 06:59:48
Also in:
lkml
Subsystem:
hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers:
Jian Shen, Jijie Shao, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
The function hclge_parse_capability() uses too many if statement, and it may add more in the future. To improve code readability, maintainability and simplicity, refactor this function by using a bit mapping array of IMP capabilities and driver capabilities.
