Changes in v5 from the cover letter
- Kept a separate page-pool recycle sync length for skb allocation failure, which must stay tied to the received buffer range.

Cover letter [PATCH net v5 0/4] net: mvpp2: fix XDP RX buffer handling
This is v5 of the earlier XDP_PASS fix. The XDP_PASS change is retained, and the series also fixes related RX/XDP buffer handling issues found during review.
Tested with tools/testing/selftests/drivers/net/xdp.py on mvpp2 hardware.

Changes in v5:
- Kept a separate page-pool recycle sync length for skb allocation failure, which must stay tied to the received buffer range.
Changes in v4:
- Reposted as a new independent thread, no code changes.
Changes in v3:
- Reworked RX refill failure handling to preserve BM pool depth by refilling before the current buffer is consumed by XDP or an skb.
Changes in v2:
- Fixed RX DMA sync range to account for RX headroom.
- Limited XDP frame size to the actual RX buffer size.
- Fixed refill error paths so retired buffers are not returned to BM.
