I attempted to set my network up with jumbo frames, and have the MTU set 
DHCP option 26 (9000), and I get my bce0 device bouncing up & down like 
a yo-yo, and
a panic with a recursed lock.

I can probably get a picture of the panic, but wanted to get this out 

(-CURRENT, both the January snap and the February snap, AMD64.)
