I have issue with this fix - my card (Comfast CF-953AX with mt7921e) stopped working running on Ubuntu 22.04 with kernel 6.5.0-18-generic. Error message as follows:

[Fix] Update WiFi/Bluetooth firmware to upstream commits: * WiFI: commit 0a18a7292a66 ("linux-firmware: update firmware for MT7921 WiFi device") * Bluetooth: commit 1366b827c213 ("linux-firmware: update firmware for mediatek bluetooth chip (MT7921)") [Test Case] 1. Have Ubuntu 22.04 LTS installed on a laptop with MT7921 Wifi adapter and connect it to a Dual-stack network leveraging Router Advertisements for IPv6. 2. Run it with HWE Kernel image linux-image-6.2.0-39-generic and observe the following: - IPv6 stateless autoconfiguration works and a public/global address is assigned. - Inbound IPv6 Multicast packets are seen when using tcpdump/wireshark. 3. Update the HWE Kernel to linux-image-6.5.0-14-generic and observe the following: - IPv6 only configures link-local address (fe80::) and no public/global address. - No inbound IPv6 multicast packets are seen when using tcpdump/wireshark. [Where problems could occur] Opaque binary. No known dependency to kernel version. [Other Info] Nominate Jammy for linux-oem-6.5/jammy and linux-hwe-6.5/jammy, and Mantic. All the commits are in upstream repository, so Noble should have them after rebased. ========== original bug report ========== The current firmware for MT7921 WiFi is giving me problems like dropping multicast packets (mDNS). I manually updated the firmware files and that fixed the issue.
