Bug Description
[SRU Justification]
[Impact]
With the rtl8723bu Wi-Fi/Bluetooth combo adapter, if the wifi is turned
off and then turned on again under the circumstance that a Bluetooth
device was paired previously, the system can't connect to a wireless
network until the system is rebooted.
[Fix]
Commit e542e66b7c2e(
single antenna"), which landed v5.5 and as its subject suggests, support
bluetooth co-existence for RTL8723BU and fixes WiFi disconnection
problem when Bluetooth is in action.
Commit a9bb0b515778(
rtl8xxxu driver") was added as a prerequisite to aforementioned fix.
Commit 4fcef8609132(
'rate_mask'") and commit eac08515d7bd(
variable 'vif','dev','len'") are included as minor fixes to previous
commits.
[Test Case]
1. Turn on Wi-Fi and get associated with some AP.
2. Pair some bluetooth device.
3. Turn off Wi-Fi and turn again.
4. Expect Wi-Fi reconnects to the previous associated AP.
[Regression Potential]
Low. Both commits only affect RTL8723BU.
========== Original Bug Description ==========
With the rtl8723bu wireless adapter, if the wifi is turned off and then turned on again, the system can't connect to a wireless network until the system is rebooted.
The issue is not upstream. With mainline kernel and in other distros, everything works fine.
