I have manually downloaded and installed the updated package and can
confirm the new package contains the correct firmware and the issue is
resolved now. IPv6 Multicast is working and IPv6 address
autoconfiguration is working as expected.

Title:
Update firmware for MT7921 in order to fix Framework 13 AMD 7040
Status in linux-firmware package in Ubuntu:
Fix Released
Status in linux-firmware source package in Jammy:
Fix Committed
Status in linux-firmware source package in Mantic:

Status in linux-firmware source package in Noble:
Fix Released
Bug description:
[SRU Justification]
BugLink: https://bugs.launchpad.net/bugs/2049220
[Impact]
MT7921 - IPv6 no longer working (Not receiving Multicast).
[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.
To be more specific, please include this commit:
https://gitlab.com/kernel-firmware/linux-firmware/-/commit/0a18a7292a66532633d9586521f0b954c68a9fbc
And possibly also this:
https://gitlab.com/kernel-firmware/linux-firmware/-/commit/1366b827c21351b37665303397e161dd4158316e
Thanks!
We also need:
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System ->
About Ubuntu
Ubuntu 22.04.3 LTS
2) The version of the package you are using, via 'apt-cache policy pkgname'
or by checking in Software Center
ii linux-firmware 20220329.git681281e4-0ubuntu3.24 all Firmware for
Linux kernel drivers
3) What you expected to happen
WiFi working
4) What happened instead
Multicast packets dropped, mDNS not working
