Subject: net: hns3: fix return value error of hclge_get_mac_vlan_cmd_status()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eefd00a5d70378feae66c073105c548075609482;p=linux.git

net: hns3: fix return value error of hclge_get_mac_vlan_cmd_status()

Error code -EIO was used to indicate mutilple errors in function
hclge_get_mac_vlan_cmd_status().This patch fixes it by using
error code depending on the error type.

For no space error, return -ENOSPC.
For entry not found, return -ENOENT.
For command send fail, return -EIO.
For invalid op code, return -EINVAL.

Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
