How to use AES hardware encryption of LTO tape drives on Linux?

I expect the LTO AES encryption to be faster than software solutions. A quick benchmark of aespipe on i7 CPU gives an impression on the effect of software AES

Without AES:

$ cat /dev/zero |  pipebench > /dev/null 
Piped   16.53 GB in 00h00m03.41s:    4.84 GB/second

With AES pipe (probably not the fastest...)

$ cat /dev/zero |  aespipe | pipebench > /dev/null 
Piped    2.73 GB in 00h00m18.27s:  153.43 MB/second
