How about run an AP on the separate host and a WLAN station (or same
using the 'wired' driver interface and Ethernet) on the device that runs
EAP-Peer?

I'm not sure why you would use eapol_test.c for this.. This is the
normal use case for APs and NAS devices in general. The main purpose of
eapol_test was to avoid having to do that with two components. If you
want to use a separate test tool, you could use hostapd on the "AP"
(e.g., with driver=none or driver=test to avoid having to have any WLAN
hardware) and then use preauth_test on the EAP client. This uses RSN
pre-authentication frames between the EAP-Peer and RADIUS client and is
pretty similar to the case of using wired IEEE 802.1X.
