Hi

When calling the function（rte_security_session_create） to create the security session of PDCP，what is the meaning of the parameter hfn_threshold passed in?
I see that the comment says "HFN threshold for key regeneration", but I still don't quite understand its meaning. Would you please explain its meaning and how to set this value for me?
I need your help,Thank you!

Best Regards,
liuhui
