I just noticed that 8750 defines one algorithm number for aes-gcm:

 30     | ENCR_AES_GCM_16_IIV        | RFC 8750

But rfc 4106 defined 3:

      18 for AES-GCM with an 8 octet ICV;
      19 for AES-GCM with a 12 octet ICV; and
      20 for AES-GCM with a 16 octet ICV.


so for 8750, what is the ICV length?

Trying to figure out the packet size with diet-esp...

thanks
