Subject: macvlan on top mlx4 fails
Hi all,
I am trying to have a macvlan on top of an ethernet driver infiniband
emulation communicating with the macvlan on anoher host with the same
configuration. But I am not able to ping them through the ip address
assigned to each macvlan.
On the host1 (s1):

When doing a tcpdump on s2 host, I have arp who-as request:
09:14:20.764389 arp who-has 1.2.3.5 tell 1.2.3.4
09:14:20.764394 arp who-has 1.2.3.5 tell 1.2.3.4
09:14:20.764427 arp who-has 1.2.3.5 tell 1.2.3.4
But doing the same tcpdump on the s1 host I don't see there arp request.
The output of lscpi:

I am a newbie on infiniband so I was wondering if I did something wrong
or if this is unsupported.
Thanks in advance.
