PATCH 1/1 crypto: Add VMAC(AES) to kernel for intel_txt support (resend)

Hi Herbert,

I am wondering whether the email system converts tab indent into spaces.
Please use the attached file (it is the same as the plain text below).
This patch is based on the latest git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git

Any problem, let me know.

Thanks.
Shane

This patch adds VMAC (a fast MAC) support into crypto framework.
