leave bge0 media autoneg no ?
Also just assign 10.86.154.221/28 to bge0, not vlan0 as I am guessing
thats your native VLAN no ?
One other thing I have found is that make the interface name
consistent with the dot1q tag. It makes for less confusion when
looking at interfaces.
e.g. for vlan 532
ifconfig vlan532 create
ifconfig vlan532 172.16.2.2/24 vlan 532 vlandev bge0

also, for debugging,
tcpdump -ei bge0
can help as it will show you encaps info.
