Protected flag is clear in Monitor Mode

[Yeoh Chun-Yeow]

Hi, all

I try to use ath10k (firmware version 10.1.467.2-1_ as standalone
monitor mode. I assume that monitor mode will allows the frame to pass
to upper layer without any modification.

But it seems that the protected flag in frame control is clear while I
capture with wireshark. I has verified that the ath9k has not such
issue and the protected flag is set.

So is this a known issue in monitor mode for ath10k?
