[PATCH net 3/6] net: hns3: change affinity_mask to numa node range
From: Guangbin Huang <hidden>

hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers:

From: Yufeng Mo <redacted>
Currently, affinity_mask is set to a single cpu. As a result,
irqbalance becomes invalid in SUBSET or EXACT mode. To solve
this problem, change affinity_mask to numa node range. In this
way, irqbalance can be performed on the cpu of the numa node.
Fixes: 0812545487ec ("net: hns3: add interrupt affinity support for misc interrupt")
