Bridge Interface not Passing Traffic

I have an Ubuntu Server 16.04 VM on ESXi with a dual SFP+ NIC passed through to it. pfSense doesn't have drivers for the NIC anymore (Mellanox ConnectX G2). I want to bridge those two SFP+ ports and the virtual NIC from ESXi to effectively make a Ubuntu based 10Gig switch. I have tried a few different methods but I can't ever get traffic to pass.
The first method I tried was this guide using VyOS. I could get a DHCP lease but couldn't pass traffic (VM to gateway, machine to VM, nothing). Next I tried the Ubuntu VM with the following config in /etc/network/interfaces and ipv4_forwarding enabled in /etc/sysctl.conf:
auto br0
iface br0 inet dhcp
bridge_ports ens160 ens160d1 ens192
bridge_sfp off
bridge_fd 0
bridge_maxwait 0
This also got me a DHCP lease but no traffic. Lastly, I installed Network-Manager (nmtui), created a br0 interface, deleted the other interfaces, and added all the interface to the bridge. That got me no DHCP lease. When I added a static IP to this config, I could ping until I connected a machine to an SFP. Once I connected the machine, no traffic passed and I could no longer ping until I unplugged the SFP and rebooted the VM.
Thanks in Advance!
