Subject: [PATCH net 5/6] net: hns3: fix wrong print link down up

From: Peiyang Wang <wangpeiyang1@...wei.com>

This patch will fix a wrong print "device link down/up". Consider a case
that set autoneg to off with same speed and duplex configuration. The link
is always up while the phy state is set to PHY_UP and set back to
PHY_RUNNING later. It will print link down when the phy state is not
PHY_RUNNING. To avoid that, the condition should include PHY_UP.
