IPv4: Send gratuitous ARP for secondary IP addresses also
[ 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. Signed-off-by: Zoltan Kiss <schaman@sch.bme.hu> Signed-off-by: David S.
