Hello,
I don't know if anyone shares the same question with me, but I think I found
the solution. The problem is, when  IEEE80211_SEND_MGMT() is called, through
this ieee80211_send_mgmt () (in ieee80211_output.c) is called. There, every
candidate mgmt packet is checked if it belongs to one of the standard mgmt
types: PROBE_REQ, BEACON, ASSOCIATION_REQ, PROB_RESP etc.
So in the "switch (type)" block (line 1924) I added the line:
case IEEE80211_FC0_SUBTYPE_RND_RESP:
//...

And everything went fine! The packet was sent and I saw it on the AP side.
