The goal was to follow the SRP spec 100%.  We added one other optional
command set (different protocol identifier than SRP) to exchange some
information like "who is at the other end", but the intent was that
the SRP part was right from the spec.

I think, since we implemented this in three operating systems (Linux,
AIX, and OS/400) using the T10 spec as the reference that we are probably
pretty close.

And yeah, I'm aware that there is another SRP implementation in the
kernel...Merging would be good...
