[PATCH net-next 3/7] net: hns3: refactor function hclgevf_parse_capability()
From: Guangbin Huang <hidden>
Date: 2021-08-28 07:00:16
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 hclgevf_parse_capability() will add more if statement 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.
