instead of ng_send_data().
The latter could lead to running the IP stack at splimp
instead of splnet, (among other problems) (that MAY be safe
but I wouldn't count on it).
Noticed while preparing a new set of netgraph stuff.
This driver should support both the SSI (V.35 etc) E1/T1 unchannelized,
DS3 and HSSI cards. Only tested on the SSI card.
