--------------------
01r,10nov10,dlk Move extern "C" after last header file include. WIND00240828.
01q,16apr07,dcc added _WRS_FASTDATA to the definition of netGtfSeconds.
01p,20feb07,kch Merged from base6_iter12_smp-dev - Use spinlocks instead of
intLock.
01o,27dec06,kch Removed references to the obsolete coreip virtual stack.
01n,10jul05,dlk Optimizations. Use L_NODE lists rather than DLL_LIST lists
to avoid needing to reference the list head when removing
a timer from the expire list. Replace timerMutex with
intLock/intUnlock.
01m,31jan05,sar Fix defects found in GTF code inspection of 10/26/2004
as described in SPRs 106685 - 105688
01l,17jan05,vvv osdep.h cleanup
01k,23aug04,rp merged from COMP_WN_IPV6_BASE6_ITER5_TO_UNIFIED_PRE_MERGE
