I have bge(4) cards.  This seems to be the correct one for me.

It still doesn't work.  Here is the relevant lines from my rc.conf.  I may 
as well use the actual values.  This is verbatim.

   ifconfig_eth0="-rxcsum -rxcsum6 -txcsum -txcsum6 -tso -vlanhwtag 
-vlanhwtso up"
   cloned_interfaces="bridge0 bridge1"
   ifconfig_bridge0_name="public"
   ifconfig_public="addm eth0 up"
   ifconfig_public_alias0="inet 0x629e8b${me}/27"
   ifconfig_public_alias0_ipv6="inet6 2605:2600:1001::${me}/64"
   defaultrouter="98.158.139.94"
   ipv6_defaultrouter=2605:2600:1001::1

Note that "me" is set to the hex value of the last octet, 65 in this case.

Here is what the interfaces look like:

eth0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 
mtu 1500
         options=80088<VLAN_MTU,VLAN_HWCSUM,LINKSTATE>
         ether 14:02:ec:31:60:d0
         media: Ethernet autoselect (1000baseT <full-duplex>)
         status: active
         nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
public: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         ether 02:9d:b2:b8:78:00
         inet 98.158.139.65 netmask 0xffffffe0 broadcast 98.158.139.95
         id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
         maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
         root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
         member: eth0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 1 priority 128 path cost 55
         groups: bridge
         nd6 options=9<PERFORMNUD,IFDISABLED>
tap0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         description: vmnet-BASE-0-public
         options=80000<LINKSTATE>
         ether 00:bd:5f:56:f8:00
         groups: tap vm-port
         media: Ethernet autoselect
         status: active
         nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
         Opened by PID 3679

In the VM I set the IP to 71 on the same network.  Here is what that looks like:

vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 
mtu 1500
         options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>
         ether 22:22:22:22:22:00
         inet 98.158.139.71 netmask 0xffffffe0 broadcast 98.158.139.95
         media: Ethernet 10Gbase-T <full-duplex>
         status: active
         nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

Everything looks correct but I can't even ping between the host and the VM.
