    ng_eiface: switch VNETs when injecting mbufs into netgraph
    
    A ng_eiface instance may be on lease to a different vnet while
    remaining tied to its parent vnet.  In such circumstances, before
    injecting mbufs into netgraph, curvnet must be set to that of the
    ng_eiface's netgraph node.  Mark the vnet transition as QUIET,
    since otherwise it would be recorded as a curvnet recursion when
    ng_eiface's ifnet resides in the same (parent) vnet as its
    netgraph node.
