This backports encap offload support from upstream. On some ath10k devices there can be about 10% improvement on tx throughput. Users can turn it on by setting frame_mode=2. Signed-off-by: Zhijun You <hujy652@gmail.com>

Subject: ath10k: turn rawmode into frame_mode
|
|
|
|
Turn boolean rawmode module param into integer frame_mode param that
|
|
contains value from ath10k_hw_txrx_mode enum. As earlier the default
|
|
param value is non-RAW (native Wi-Fi) encapsulation. The param name
|
|
is selected to be consistent with the similar ath11k param.
|
|
|
|
This is a preparation step for upcoming encapsulation offloading
|
|
support.
