That's ACK delay problem. 2x30km roundtrip is too long, firmware thinks
that packets are lost.
It is interesting how BSD handle that. Did they manage to increase
ACK timeout? Or maybe they run the card in monitor mode and
mostly bypass firmware?
Tell us more about BSD driver. Can you sniff at BSD traffic?
