Subject: [PATCH net-next v3 0/2] net: stmmac: introduce XDP rx multi-buff support
Date: Sun, 04 Oct 2026 22:42:00 +0200	[thread overview]
Message-ID: <20261004-stmmac-rx-mb-v3-0-50fa171af9ec@oss.qualcomm.com> (raw)

Rework stmmac_rx routine to properly support XDP rx multi-buff.
Fix possible rx_q state leaks closing/opening the interface.

---
Changes in v3:
- Return secondary page in case of error.
- Introduce stmmac_xdp_shrink_tail() to remove the ethernet FCS.
- Add patch 'net: stmmac: take ownership of saved RX state at poll
  entry' from James.
- Link to v2: https://lore.kernel.org/r/20260921-stmmac-rx-mb-v2-1-6e826e1ff306@oss.qualcomm.com

Changes in v2:
- Rely on xdp_buff_add_frag() to create xdp fragments
- Fix bugs in rx_q state recording
- Fix the corner case where we receive more than MAX_SKB_FRAGS fragments
- Cosmetics
- Link to v1: https://lore.kernel.org/r/20260918-stmmac-rx-mb-v1-1-0b4517d404af@oss.qualcomm.com
