I have a "MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter" (14c3:0616) and when the commit c222f77fd4 ("wifi: mt76: mt7921: fix rx filter incorrect by drv/fw inconsistent") is applied (found by bisecting, checked by reverting it on v6.3) I have the following problem on my machine: when I connect to my router no DHCPv4 exchange happens, I don't see responses in tcpdump. My network setup is non-trivial though, and it looks like the problem is specific to it, but I still wonder if it's some bug in the aforementioned patch as my setup works with all other devices and I would expect it to work as long as the network packets sent by the device are the same. My setup is as follows: I have an ISP router which provides a 2.4GHz network and another router (Xiaomi R4AC with OpenWRT) connected by Ethernet to it that provides a 5GHz network and is configured as a "Relay bridge" (using relayd) to forward packets to the ISP router and back. This includes DHCPv4 packets, which are handled by the ISP router. tcpdump on the machine with MT7922 shows that the DHCP requests are sent while the responses are not received, while tcpdump on the bridge router shows both requests and responses. I've tried connecting the machine to the ISP router network directly and also to another AP (one on my phone) and those work correctly on all kernels. Please let me know if I need to do any other debugging or troubleshooting steps. Thank you.
