Subject: cryptodev: remove single-DES support in cryptodev
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d7a2127a4c5b2d52c94d5c27a5744a055ddc14f7;p=qemu.git

cryptodev: remove single-DES support in cryptodev

Single-DES is obsolete and it's broken/useless for decades, we should
remove it in cryptodev, as suggested by Daniel.
Guest who wants to use this obsolete cipher alg will use its built-in
implementation instead.
