Re: [PATCH net-next v3 4/6] net: bcmgenet: add XDP_TX support

Also in:
bpf, lkml
+static bool
+bcmgenet_xdp_xmit_frame(struct bcmgenet_priv *priv,
+ struct xdp_frame *xdpf, bool dma_map)
+{
+ struct bcmgenet_tx_ring *ring = &priv->tx_rings[DESC_INDEX];
+ struct device *kdev = &priv->pdev->dev;
+ struct enet_cb *tx_cb_ptr;
+ dma_addr_t mapping;
+ unsigned int dma_len;
+ u32 len_stat;
+
+ spin_lock(&ring->lock);
+So we acquire lock on per-packet basis on the XDP_TX path? Do you think we can batch this?
