Can you really be sure that there is no packet loss in the N7Ks? We have experienced a similar situation and it turned out that the N7Ks indeed dropped packets, but those could not be seen in any counters. It took quite some effort with sniffers and taps to prove this.
However, as a workaround you should consider enabling MAC masquerading in the according traffic-group(s) of the BigIP. Thus, there is no longer need for sending grat ARPs in case of failover.
