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.
