[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

[ Upstream commit 2d0ec5440bef4a0a8858d52d45c31725540c3e74 ]

Network core refuses to change mac address because flag
IFF_LIVE_ADDR_CHANGE isn't set. Set this missing flag.

Fixes: 1f7aa2bc268e ("r8169: simplify rtl_set_mac_address")
