ath10k: qca6174 firmware: difference between hw2.1/firmware-5 and hw3.0/firmware-4

[Xuebing Wang]

Hi Kalle,

I cloned your ath10k-firmware from your github. Would you please advise 
what are the differences of hw2.1/firmware-5 and hw3.0/firmware-4 for 
qca6174? Does hw3.0/firmware-4 support Monitor Mode?

I have a wlan card with BMI version (QCA6174_HW_2_1_VERSION 0x05010000) 
and Monitor Mode works no problem with latest kernel v4.8-rc2.

I have another wlan card with (QCA6174_HW_3_2_VERSION 0x05030000). I am 
trying to back-port ath10k from v4.8-rc2 to 3.10.73 for this HW_3_2 
QCA6174 wlan card. Virtual interface (mon0) can be added and brought-up, 
but tcpdump can not capture any packets. I am wondering if it could be 
related to (hw2.1/firmware-5 vs hw3.0/firmware-4)?

I can not try v4.8-rc2 for this HW_3_2 wlan card, because it is used in 
an android phone.

Thanks a lot for your help.
