Subject: [PATCH net-next v10 1/3] net: phy: modify assignment to OR for dev_flags in phy_attach_direct

From: Tao Ren <taoren@...com>

Modify the assignment to OR when dealing with phydev->dev_flags in
phy_attach_direct function, and this is to make sure dev_flags set in
driver's probe callback won't be lost.
