4.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Yunsheng Lin <[email protected]> [ Upstream commit be8d8cdb8ebf3afd841c109dd035fd789a0c7d53 ] When hclge_ae_start is called, hdev->hw.mac.link may be set to one after up/down multi-times, which does not correspond to the link state of netdev when the netdev is up. This fixes it by setting hdev->hw.mac.link to zero when hclge_ae_start is called.
