Ok, PEBKAC: I forgot to reset kern.usercrypto...

Now, with kern.usercrypto set, using or not using cryptodev does show
a difference:

I see similar numbers for DES3 and AES; the vpn1411 seems to be faster
for block sizes larger than 256, and slower else. Are these numbers
about what I should expect?


Thanks and sorry for the noise...
