The current recommendation is to configure the software module as a FirePOWER Services module (if it isn't already). That would be module type "sfr" in the output of "show module".
You would then need the Control and Protect licenses plus a FireSIGHT Management Center (separate VM). The FMC is used to administer and monitor the FirePOWER Services module(s).
Your Cisco reseller or partner should be able to assist you with the correct ordering details. The required parts would be something like this:
ASA5512-CTRL-LIC (Control license)
L-ASA5512-TA= (IPS top line part number)
L-ASA5512-TA-1Y (1 year subscription for updates, also available in 3- and 5-year)
FS-VMW-2-SW-K9 (FireSIGHT Management Center licensed for up to 2 modules)
CON-SAU-VMWSW2 (Support for the FMC)
