gentoo bonded nics dropping packets

Question

I have two nics bonded in gentoo, eth2 and eth3 to bond0. eth2 is connected to a different switches than eth3 for redundancy with eth2 in standby and eth3 in active mode. eth3 is running fine with no drops but eth2 is dropping packets constantly.I swapped cables and checked the switch ports which show no errors. I did a TCPDUMP on eth2 and all I saw was arp requests.

eth2: flags=6211 mtu 1500 ether 90:b1:1c:19:59:1e txqueuelen 1000 (Ethernet) RX packets 32664867 bytes 2090551811 (1.9 GiB) RX errors 0 dropped 32664913 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 36 memory 0xd7000000-d77fffff

eth3: flags=6211 mtu 1500 ether 90:b1:1c:19:59:1e txqueuelen 1000 (Ethernet) RX packets 3186342439 bytes 683402238345 (636.4 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 2465388994 bytes 575317691871 (535.8 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 37 memory 0xd8000000-d87fffff

• I believe the problem is most likely caused by the broadcast arp requests coming from eth2 (standby) slave in the bond. Does anyone know how to turn off broadcast arp on a slave bond?
