Our QA reported regression on ath9k connecting to legacy WEP-LEAP AP,
with the following supplicant parameters:

fast_reauth=1
ap_scan=1

eapol_version=1

network={
        ssid="qe-wep-enterprise-cisco"
        key_mgmt=IEEE8021X
        auth_alg=LEAP
        eap=LEAP
        identity="AAA"
        password="BBB"
}

Device associate but DHCP fails (we do no recive any frame).
