Subject: [PATCH] net: ethernet: mtk_wed: move MTK_WDMA_RESET_IDX_TX
configuration in mtk_wdma_tx_reset
Remove duplicated code. Increase poll timeout to 10ms in order to be
aligned with vendor sdk.
This is a preliminary patch to add Wireless Ethernet Dispatcher reset
support.

Subject: [PATCH] net: ethernet: mtk_wed: get rid of queue lock for rx queue
Queue spinlock is currently held in mtk_wed_wo_queue_rx_clean and
mtk_wed_wo_queue_refill routines for MTK Wireless Ethernet Dispatcher
MCU rx queue. mtk_wed_wo_queue_refill() is running during initialization
and in rx tasklet while mtk_wed_wo_queue_rx_clean() is running in
mtk_wed_wo_hw_deinit() during hw de-init phase after rx tasklet has been
disabled. Since mtk_wed_wo_queue_rx_clean and mtk_wed_wo_queue_refill
routines can't run concurrently get rid of spinlock for mcu rx queue.

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.

Subject: [PATCH] net: ethernet: mtk_wed: add reset to rx_ring_setup callback
This patch adds reset parameter to mtk_wed_rx_ring_setup signature
in order to align rx_ring_setup callback to tx_ring_setup one introduced
in 'commit 23dca7a90017 ("net: ethernet: mtk_wed: add reset to
tx_ring_setup callback")'
