Subject: [PATCH 2/6] net: airoha: npu: Add wlan_{send,get}_msg NPU callbacks
|
|
|
|
Introduce wlan_send_msg() and wlan_get_msg() NPU wlan callbacks used
|
|
by the wlan driver (MT76) to initialize NPU module registers in order to
|
|
offload wireless-wired traffic.
|
|
This is a preliminary patch to enable wlan flowtable offload for EN7581
|
|
SoC with MT76 driver.
