From: Ard Biesheuvel <ardb@kernel.org>
Even the people that are invested in Aegis appear to have lost interest
in aegis128: it did win the CAESAR competition but is no longer covered
by RFC 10032, which does list some other variants that competed as well.
So let's delete it.

From: Ard Biesheuvel <ardb@kernel.org>
Even the people that are invested in Aegis appear to have lost interest
in aegis128: it did win the CAESAR competition but is no longer covered
by RFC 10032, which does list some other variants that competed as well.
So let's delete it.
