This block implements the idle bytes padding to the AAD and Bypass fields, which are not 16 byte-aligned if you turn on Enable Gen. GCM AAD-Bypass ingress padding in the IP parameter editor. You must send in the real AAD and Bypass fields length.
If
you do not turn on
Enable
Gen. GCM AAD-Bypass ingress padding
in
the IP
parameter
editor, the padding logic within the IP is optimized away
to
save device resources.
