enable aesni.
that means that all users running ipsec on amd64 with 'aes'
cpu flag will have aes encryption accelerated in cbc and ctr
modes for all three key sizes: 128, 192 and 256.
for debug purposed a number of operations performed by the
driver is visible throught the pstat(8) utility:
pstat -d u aesni_ops
note that you need to run config(8) to hook up new files.
