Just one comment, any patch that removes the existing
Intel AESNI code Netgear created should come along with
benchmarks showing the fileserver code is unaffected
performance-wise when signing/sealing by the change
(by unaffected I mean less than 1-2% performance
drop) otherwise I'm going to strongly NAK :-).

I fought too hard to get that code in to gain us
performance to drop if for build cleanlyness and
convenience :-).

Jeremy.
