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

Figured it out, I had misunderstood what "monitor" meant in the context of changing an RX filter. Patch sent.
