Subject: IPv4: Send gratuitous ARP for secondary IP addresses also
From: Zoltan Kiss <[email protected]>
[ 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.
