Hi Brian, as you've probably seen from the net-snmp README file for the HP-UX support I'm the guy who implemented HP-UX support for net-snmp - but this was about seven years ago, and I'm no longer engaged in the net-snmp development.
As far as I can recall the implementation uses the HP-UX provided include file /usr/include/sys/mib.h and the function get_mib_info() in order to retrieve the MIB information defined in that include file. At least at that time there was nearly no documentation regarding that interface, neither for the include file nor for the function. So I had to guess how to call the function etc. One missing piece at that time was the ipRouteDiscards value, and from investigating the include file I did assume that something was broken with respect to that value. Since those days when I implemented the HP-UX support in net-snmp the source structure has been changed thoroughly. So I can't say whether ifTable was implemented using get_mib_info(). And I'm not sure whether ifXTable was already supported in net-snmp at that time.
