Bug description:
[SRU Justification]
BugLink: https://bugs.launchpad.net/bugs/2109314
[ Impact ]
v6.14-rc1 commit 5190594bcec2 ("wifi: mt76: mt7921: add rfkill_poll
for hardware rfkill"), along with linux-firmware commit 15442c631c6b
("linux-firmware: update firmware for MT7920 WiFi device"),
implemented a feature that allows disable WiFi function from BIOS. The
latter is under upstream tag 20250311, and linux-firmware/plucky
version 20250310.git9e1370d3-0ubuntu1.
[ Test Plan ]
1. Enable "Wireless Radio Control" option in BIOS Setup;
2. Connect a Ethernet cable to SUT's LOM port in Ubuntu OS
3. WiFi interface should be hardware disabled(rfkilled).
```
$ rfkill
ID TYPE DEVICE SOFT HARD
0 wlan phy0 unblocked blocked
1 wlan wlp0s20f3 unblocked blocked
2 bluetooth hci0 unblocked unblocked
```
[ Where problems could occur ]
Chip firmware provides an additional capability flag indicating the
support. Without that, this change takes no effect.
[ Other Info ]
While the kernel patch is already in v6.14-rc1, nominate for oem-6.11
only.
========== original bug report ==========
[Steps to reproduce]
1. Enable "Wireless Radio Control" option in BIOS Setup;
2. Connect a Ethernet cable to SUT's LOM port in Ubuntu OS, the Wi-Fi
option is still enabled --> issue.
[Expected result]
Wi-Fi option should be disabled when connect a Ethernet cable to SUT's
LOM port with "Wireless Radio Control" on.
[Actual result]
Wi-Fi option is enabled when connect a Ethernet cable to SUT's LOM
port with "Wireless Radio Control" on.
