--------------------------------
|
|
|
|
[ Upstream commit 568a54bdf70b143f3e0befa298e22ad469ffc732 ]
|
|
|
|
The message sent to VF should be initialized, otherwise random
|
|
value of some contents may cause improper processing by the target.
|
|
So add a initialization to message in hclge_get_link_mode().
