Eap102 - Support for monitor mode & Packet injection

We are trying to inject some frames using the aircrack-ng suite with the eap102 but it doesn’t seem to work.
We are using a TIP image (V2.5.0), monitor seems to work fine (I am able to sniff using the monitor interface) but injection seems to do nothing.
Can you please confirm this is supported? If not, what can be done to support this (as we build from sources anyway)?
