Hi,
I am facing an issue on my board that is using v3.10.61 Linux kernel.
The arping -c 3 -f <IP address> doesn't update the arp table even though
I get a proper response
root@keystone-evm:~# arping -b -c 3 -I eth0 -f 158.218.104.3
ARPING to 158.218.104.3 from 158.218.104.192 via eth0
Unicast reply from 158.218.104.3 [0:12:1:f7:d6:ff] 0.751ms

root@keystone-evm:~# arp -n -a
? (158.218.104.1) at 00:00:0c:07:ac:68 [ether] on eth0
? (158.218.104.233) at d4:be:d9:3d:b6:c1 [ether] on eth0
But by enabling following sysfs entry, it works.
echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_accept
Is this the expected behavior? On my ubuntu Linux pc with v3.2 running I
don't have to do this and it always update the arp table.
Thanks for your help.
