Hi,
We are using linux-2.6.28 and we would like to hardware accelerate the

I understand that strongswan uses the Linux/NETKEY IPsec implementation,

What I would like to know is:
1) does the xfrm/ESP implementation support asynchronous/parallel packet

2) If yes, does it support it in both directions (tx/rx)?
Yes on both counts.

AFAK, the crypto interface is asynchronous but the hashing interface (as used

There are two patches I've recently seen on the list, one for converting to
async hashing and one for parallel crypto/ipsec which will

However, I think that the best results for hw accel will be obtained if
you accelerate the AEAD interface.
If your driver benefits from seeing both the hashing request and the

PCLMULQDQ is used to accelerate the most time-consuming part of GHASH,
carry-less multiplication. More information about PCLMULQDQ can be
