Is it possible to force greater than 128-bit strength when using AES-CCM mode?

Greetings list.
I was wondering why there is no switch or parameter to increase the
"bit-strength" of the encryption algorithm under AES above 128-bit.
I also would like to know if I am simply misunderstanding the
implementation. The man page has always indicated that a "256-bit" hex
key can be used in place of a passkey, however, I am a bit confused as
to why the interface information always will indicate 128-bit AES-CCM.
Please reference the following:
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
inet 192.168.200.1 netmask 0xffff0000 broadcast 192.168.255.255

Does hostapd implement anything higher than a 128-bit encryption
strength, or am I simply confused as to what I am using for reference?
I am running hostapd version 0.7.3 on a FreeBSD-8.2 router.
