iptables does not see 802.11 ACK frames, and depending on the used 
driver they are even invisible to the layers below IP, as they are 
generated/handled in hardware/firmware of the wireless interface.

I do not see a "normal" way to block them beside modifying the wireless 
driver or mac80211 layer (if used by your driver).
