Subject: xfrm: Add SHA384 and SHA512 HMAC authentication algorithms to XFRM
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bc74b0c8af17458ecae77f725e507ab5fd100105;p=mv-sheeva.git

xfrm: Add SHA384 and SHA512 HMAC authentication algorithms to XFRM

These algorithms use a truncation of 192/256 bits, as specified
in RFC4868.
