I am using two bcm 43438A, the two devices are putted into a shield box, then I  tested them in wifi mfg mode. One device sends 1000 package, the other one only receives around 960 packages.

Below is the  wl version

# wl ver                                                                                                                        

6.37 RC32.0                                                                                                                       

wl0: Apr 23 2015 20:40:36 version 7.46.3 (r551729 WLTEST) FWID 01-af384561
