Comment # 3 on bug 10786 from 
Thanks, confirmed for FCS.. 

About 
>In the VHT NDP announcement frame, the 3 bits of STA info filed for Nc index shows as Reserved.

>From spec (802.11ac-2013.pdf):
Nc Index : If the Feedback Type field indicates MU, then Nc Index indicates the
number of columns, Nc, in the Compressed Beamforming Feedback Matrix subfield
minus 1 [...] Reserved if the Feedback Type field indicates SU

For me, the display is good
