HP-UX 11.31 now allows concurrent usage of libpcap

HP-UX 11.31 now allows concurrent usage of libpcap

The dlpi_max_ub_promisc tuning parameter can be set by kctune to allow concurrent usage of libpcap. I see in dlpi_ctl.c that there is a check for exceeding the max unbound promiscuous settings, and if exceeded, then an error=EBUSY; is returned. My understanding is that this tuning parameter is not available in 11.23.

 

How do the 11.31 changes allow for concurrent usage of opening /dev/dlpi? Are there any new data structures, for example? If so, do you know their names?

 

If you know the kernel module and function names which allow for concurrent usage, that information would also be appreciated.

 

Thanks and Regards,
