Subject: [PATCH] ath10k: Update the phymode along with bandwidth change
|
||||
request
|
||||
|
||||
In the case of Station connects to AP with narrower bandwidth at beginning.
|
||||
And later the AP changes the bandwidth to winder bandwidth, the AP will
|
||||
beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80.
|
||||
|
||||
Since the supported BANDWIDTH will be limited by the PHYMODE, so while
|
||||
Station receives the bandwidth change request, it will also need to
|
||||
reconfigure the PHYMODE setting to firmware instead of just configuring
|
||||
the BANDWIDTH info, otherwise it'll trigger a firmware crash with
|
||||
non-support bandwidth.
|
||||
|
||||
The issue was observed in WLAN.RM.4.4.1-00051-QCARMSWP-1, QCA6174 with
|
||||
below scenario.
