Subject: [PATCH] net: ethernet: mtk_wed: get rid of queue lock for tx queue
|
|
|
|
Similar to MTK Wireless Ethernet Dispatcher (WED) MCU rx queue,
|
|
we do not need to protect WED MCU tx queue with a spin lock since
|
|
the tx queue is accessed in the two following routines:
|
|
- mtk_wed_wo_queue_tx_skb():
|
|
it is run at initialization and during mt7915 normal operation.
|
|
Moreover MCU messages are serialized through MCU mutex.
|
|
- mtk_wed_wo_queue_tx_clean():
|
|
it runs just at mt7915 driver module unload when no more messages
|
|
are sent to the MCU.
|
|
|
|
Remove tx queue spinlock.
