hostapd with AES-capable WiFi card = hardware AES or software AES?

I've seeking over the internet but no answers found.

I have a board with Atom N2800 (with no AES-NI), and a high-end 802.11n wifi card (AR9590) with AES encryption/decryption offload support.

Now I'd like to build a wifi router with installing archlinux, and with this configuration. The question is,

Will hostapd offload the AES encryption/decryption to the wifi card? or use openSSL + CPU?

Ping...

another question:
Does a CPU with AES-NI hardware acceleration actually benefit hostapd?
