Subject: [PATCH net v2 0/4] net: mvpp2: fix XDP RX buffer handling
Date: Tue, 2 Jun 2026 18:46:31 +0200 [thread overview]
Message-ID: <20260602164635.62517-1-mail@tk154.de> (raw)
This is v2 of the earlier XDP_PASS fix. The XDP_PASS change is retained,
and the series now also fixes related RX/XDP buffer handling issues found
during review.
---
v1: https://lore.kernel.org/all/20260524122334.1730451-1-mail@tk154.de/
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.
Til Kaiser (4):
net: mvpp2: sync RX data at the hardware packet offset
net: mvpp2: limit XDP frame size to the RX buffer
net: mvpp2: do not return retired RX buffers to BM
net: mvpp2: build skb from XDP-adjusted data on XDP_PASS
