Hi,
Using QCA9888 on kernel 5.15 with FW 10.4-3.10-00076, if a mesh
interface is created while a STA is scanning on the same phy, the mesh
interface connects correctly to other mesh nodes but not a single
broadcast packet is received by ath10k (unicast packets are received
correctly). Creating a monitor interface on this phy and bringing it up
allows the mesh interface to receive those broadcast packet.
I tried to add debug in ath10k_htt_rx_h_enqueue() to see ath10k was
seeing those broadcast packets but it doesn't (ath10k_htt_rx_h_enqueue()
sees them only when monitor interface is up).
So I have a hunch it could be that this is a FW issue, I tried with
10.4-3.9.0.2-00157 FW which seem more recent than 10.4-3.10-00076 but
the issue is still here.
Has anyone with a better understanding of the 9888 firmware and/or
ath10k driver any idea how to debug this further ?
I use the script below to reproduce the issue but as it seems to be very
timing sensitive I am not sure other plateform will behave the same.
Thanks
