[ovs-dev] [PATCH 49/50] openvswitch: use dev_hw_addr_random() instead of random_ether_addr()

[Danny Kukawka]

Use dev_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.
