AFAIK it's not yet, not sure whether Jack has plan to implement the
offloading. I know old Intel i82550 also supported IPSec offloading
but Intel didn't release required information to implement it. 3Com
also supported IPSec offloading in their 3XP hardwares(txp(4)) but
the offloading was not implemented.
