Subject: [PATCH] ath10k: fix DMA related firmware crashes on multiple devices
|
|
|
|
Some platforms really don't like DMA bursts of 256 bytes, and this
|
|
causes the firmware to crash when sending beacons.
|
|
Also, changing this based on the firmware version does not seem to make
|
|
much sense, so use 128 bytes for all versions.
