[PATCH net-next 1/7] net: hns3: add api capability bits for firmware
From: Huazhong Tan <hidden>
Date: 2021-02-02 12:44:35
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
From: Jian Shen <shenjian15@huawei.com> To improve the compatibility of firmware for driver, help firmware to deal with different api commands, add api capability bits when initialization the command queue.
