Subject: [Patch V2 net 08/11] net: hns3: fix incorrect return value/type of some functions
There are some functions that, when they fail to execute a send command,
need to return the corresponding error value to its caller.
Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
Fixes: 681ec3999b3d ("net: hns3: fix for vlan table lost problem when resetting")
Signed-off-by: Huazhong Tan <tanhuazhong@...wei.com>
