modification history
--------------------
01q,07oct04,spm  restored internal route classification; removed related SPR
                 #88035 changes [additional class-based routes] (SPR #102398)
01p,06dec03,niq  Merge from base6_itn3_networking-dev.al branch
01o,04nov03,rlm  Ran batch header path update for header re-org.
01n,03nov03,rlm  Removed wrn/coreip/ prefix from #includes for header re-org.
01m,27oct03,cdw  update include statements post header re-org.
01l,01may03,spm  Tornado 2.2 CP1 merge (from ver 01l,28mar03,rae:
                 TOR2_2-CP1-F label, tor2_2-patch branch, /wind/river VOB)
01k,09sep02,hsh  add c++ protection
01j,16may02,ant  hash definitions rt_xxx changed to rtu_xxx
01i,18dec01,hgo  modification of header files
01h,07aug01,niq  Add the RTS_PRIMARY flag definition
01g,10jul01,niq  Changes to use published routing extension interfaces
                 rather than private ones and support for static and other
                 non-rip routes.
01f,29mar01,spm  merged changes from version 01f of tor2_0.open_stack

01d,29sep98,spm  added support for IP group MIB (SPR #9374); removed unused 
                 entries from rt_entry structure (SPR #22535)
01c,11sep98,spm  updated contents to prevent compilation problems (SPR #22352)
