802.11 duplicate packet detection

My setup, STAs & AP are using HostAP code.
I have multiple STAs sending UDP packets to AP.
Occasionally, I find lot of duplicate UDP packets at AP.
I guess any 802.11 duplicate packets
should be dropped at the link layer itself.
But when I looked at the code, especially
hostap_80211_rx.c & hostap_wlan.h files,
I didnot find any received 802.11 packet cache in the code
but found only fragment cache.
I am probably looking at the wrong place.
Jouni, can you please point me in the right direction.
I am basically looking at the Duplicate packet detection
and recovery in HostAP driver code.
