[v2,0/4] move skb mapping before configuring txwi

Message

Move skb dma mapping before configuring txwi since new chipsets
(e.g. mt7615) will need dma addresses to properly configure txwi.
Introduce temporary tx_aligned4_skbs variable in order to tell mt76 layer
if it is necessary to align the 802.11 header (it will be removed as soon
as mac80211 will take care of it)

Changes since v1:
- move queue depth check after tx_prepare_skb pointer
- make mt76_inser_hdr_pad() return void

Lorenzo Bianconi (4):
  mt76: move mt76x02_insert_hdr_pad in mt76-core module
  mt76: mmio: move mt76_insert_hdr_pad in mt76_dma_tx_queue_skb
  mt76: move skb dma mapping before running tx_prepare_skb
  mt76: introduce mt76_tx_info data structure
