RX multicast action frames (ath10k)

[James Prestwood <prestwoj@xxxxxxxxx>]

Hi,

Currently it is not possible to receive multicast action frames (AFAIK) 
unless EXT_FEATURE_MULTICAST_REGISTRATIONS is supported, which is 
currently only ath9k (and hwsim). This was added to support DPP which 
I'm also trying to do on a system using ath10k (potentially ath11k in 
the future). The original change [1] to ath9k was quite simple and just 
set FIF_MCAST_ACTION to the list of filters.

I tried doing this for ath10k with no luck, and looking deeper it 
appears the firmware API (ATH10K_FW_WMI_OP_VERSION_TLV) doesn't have the 
"rx_filter" command. I'm using a QCA6174.

I also noticed the "configure_filter" op for ath10k seems to be monitor 
specific.

So I'm wondering if this is something the firmware needs to support (if 
so I guess I'm SOL unless someone wants to add that). If not I could use 
some guidance on how I could support it if its possible to modify the 
ath10k driver.

Thanks,
James
