intel 82576 ipsec offload?

[Jack Vogel]

I am Jack, the network engineer at Intel responsible for all FreeBSD wired
lan drivers.
This is the first I've seen about this. Our understanding was that the
infrastructure needed
to do IPSec was not available for either Linux or FreeBSD, can you please
explain things?

If everything is there except the support in the driver then I might be able
to add that to
my queue.

Cheers,

Jack
