Yep... I have looked through most of /drivers/net/bonding and I can't
really see why it should be blowing up there.. it really should cause
the BUG_ON under normal IPoIB if the MTU was the cause - yet I have
not experienced this.
The bonding code doesn't seem to do anything special with the MTU
other than propagating changes to the slaves.
