we should consider that CCM support is quite new in nettle and it will take
long time till we'll see it in stable distos. And does nettle's CCM support
also using HW crypto support btw?

Other libs that would be worth taking a closer look at: mbed TLS (previously
PolarSSL) and wolfCrypt. The wolf people already offered to support
implementation work in Samba. They have a big range of HW crypto support also.
