    Subject[50/90] IPv4: Send gratuitous ARP for secondary IP addresses also
    3.0-stable review patch.  If anyone has any objections, please let us know.

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


    From: Zoltan Kiss <schaman@sch.bme.hu>

    [ Upstream commit b76d0789c92a816a5539dc14232a700b8d62a53a ]

    If a device event generates gratuitous ARP messages, only primary
    address is used for sending. This patch iterates through the whole
    list. Tested with 2 IP addresses configuration on bonding interface.
