> [Impact]
>
> On platforms with RTL8851BE/RTL8852BE, bluetooth mouse/keyboard may not work
> smoothly with WiFi connection activated.
>
> [Fix]
>
> Proposed firmware upstreamed as:
> * 2afd1423e476 ("rtw89: 8852b: update fw to v0.29.29.5")
> * 7a916315fb28 ("rtw89: 8852b: update fw to v0.29.29.4")
> * 02df6e4f03c0 ("rtw89: 8851b: update fw to v0.29.41.3")
>
> [Test Case]
>
> 1. Install Ubuntu 22.04 on SUT with RTL8851BE / 8852BE Wlan card
> 2. Connected BT KB/MS, and then connected WIFI, select an AP to connect
> 3. Check BT mouse/keyboard, mouse movement, keyboard key pressing not respond
> smoothly.
>
> [Where problems could occur]
>
> This updates opaque firmware blobs, so anything could happen. With verifications
> from multiparties, it improves the stability and no other problem found so far.
>
> [Other Info]
>
> On Lunar, we don't have RTL8851BE enabled, so the related commits are omitted.
> On Mantic and oem-6.5/jammy, we have both.
