Assumptions:
1) linux plaform
2) ESP
3) you want to accelerate the crypto+hash for each packet at the ESP 
level, not RSA crypto operations of IKE

Strongswan uses the linux kernel to do ESP packet processing, therefore 
the questions to ask is: does the linux ESP implementation support 
hardware acceleration?

Yes, linux ESP uses the linux kernel crypto api, which can support 
hardware acceleration. Look at the talitos driver in the linux kernel 
for an example.

Beware that the linux crypto api is actively developed as we speak and 
is constantly changing.
