Subject: [PATCH net-next 2/5] net: hns3: remove the affinity settings of vector0

From: Yufeng Mo <moyufeng@...wei.com>

Vector0 is used for common interrupt control events and is
irrelevant to performance. Currently, the driver sets the
default affinity of vector0 to NUMA nodes, which is unnecessary.
Therefore, the default setting is removed, and the driver does
not set the affinity for vector0.
