[PATCH v3 wireless-drivers 0/3] mt76: usb: fix A-MSDU support

[Lorenzo Bianconi <lorenzo@kernel.org>]

Reallocate the skb if there is no enough space to manage the AMSDU rx packets.
Do not always copy the first part of received frames if A-MSDU is enabled
for SG capable devices

Changes since v2:
- simplify mt76u_build_rx_skb
- add patch 2/3: mt76u: introduce mt76u_ep data structure
- align usb buffer size to usb max endpoint length
- set buf_size to PAGE_SIZE even for sg case

Changes since v1:
- do not allocate multiple page buffers but rely on fragmented skbs
  if there is no enough space to manage the AMSDU rx packets
