Description (partial)

Nexus 7000 may send a unicast arp reply out the wrong interface if the ethernet source mac of the arp request is different from the sender mac address in the arp payload.

This will only occur when then the ethernet source mac is not the same as the arp sender address in the arp payload

There is no workaround.
