Subject: Hardware Acceleration on Freescale MPC8349

Hello,

I am trying to get HW accelerated IPsec connections working
on the SEC 2.4 engine in the MPC8349.

I am hoping to use StrongSwan which uses the native XFRM
kernel components. Unfortunately it looks like the only
working option available to me is the OCF stuff (using the Talitos
driver) which only works with OpenSwan.

Is anyone working on a HW accelerator for the Freescale SEC engine
that XFRM IPsec connections can use?

Thanks,

Barry

I have one that's not suitable for submission yet; I'm working on
authenc(hmac(sha1),cbc(aes)) support and intend on submitting it
before the next window opens.

That sounds cool!

Please don't let the window stop you though. Because the earlier
your patch goes into a tree the sooner it can be pushed to Linus
when the window does open.

In other words, the merge window should have no effect on your
patch submission. In fact, if you wait for the merge window to
open first, it'll only mean that I can't push it to Linus for that
release and it'll have to wait for the next one.

Cheers,
