modification history
--------------------
01m,03may02,mas  made pPkt volatile pointer in loanBuild() (SPR 68334)
01l,21mar02,vvv  added doc for copyFromMbufs (SPR #20787)
01k,02oct01,mas  added support for all 8 NETIF arguments in smNetAttach2 (4547)
01j,20aug96,vin  commented out do_protocol
01i,11aug93,jmm  Changed ioctl.h and socket.h to sys/ioctl.h and sys/socket.h
01h,22sep92,rrr  added support for c++
01g,27jul92,elh  Added smNetShowInit.
01f,15jun92,elh  changed parameter to smNetInetGet.
01e,02jun92,elh  the tree shuffle
01d,27may92,elh  Incorperated the changes caused from restructuring the
		 shared memory libraries.  Renamed from smVxLib.h
01c,02may92,elh  added mask to smNetInit
01b,10apr92,elh  added startAddr for sequential addressing.
01a,17nov90,elh  written.
