net/hns3: support link speed autoneg for PF
This patch supports link speed auto-negotiation for PF. If the device supports auto-negotiation, the device negotiates with the link partner at all speeds supported by the device. Signed-off-by: Huisong Li <lihuisong@huawei.com> Signed-off-by: Min Hu (Connor) <humin29@huawei.com>
